T-Mobile US Inc. users in several states reported problems making and receiving phone calls Monday, a widespread service disruption for the newly enlarged wireless provider.

The network issues began in the afternoon at T-Mobile, which is taking early steps to integrate its April purchase of Sprint Corp. The transaction left the combined company with more than 100 million customers, including those running atop its infrastructure under other carriers’ brands.

Banks are slashing credit lines to shale drillers, as an oil-price crash and wells that have failed to produce as much as predicted force a painful reassessment of companies’ assets.

The cuts vary from company to company, but Moody’s Corp. and JP Morgan Chase & Co. forecast a total reduction of as much as 30% to the asset-backed loans, or tens of billions of dollars. At current prices, that will be enough to tip some weaker players into bankruptcy as capital for the beleaguered industry dries up, say bankers, lawyers and...

Auto makers are grappling with absent U.S. factory workers and Covid-19 cases at their reopened plants, complicating the companies’ efforts to recoup production lost to the pandemic.

The impact on output has been minimal as many plants aren’t yet operating at full capacity, the companies said. Still, the challenges have required auto makers to adjust shifts and add temporary workers. Such moves highlight the complexities businesses face upon reopening as they look to insulate their workplaces from potential outbreaks while...

When Covid-19 restrictions closed most dining rooms across the U.S., Denny’s had to think fast.

Full-service chains such as Denny’s and Olive Garden rely on sit-down business and typically don’t offer drive-through service—which means the restrictions on gatherings hit them harder than their quick-service competitors. Not to mention that full-service chains usually charge higher prices, and many potential customers found themselves in financial straits during the lockdown.

Ann Arbor, Mich.—When one of Michigan’s biggest restaurant franchises reopened for dine-in service this week after nearly three months, its eateries had been transformed by efforts to make redesigned door handles and a checkerboard of closed-off booths look as inviting as possible.

At an Applebee’s owned by Team Schostak Family Restaurants in Ypsilanti, Mich., a sign next to the entrance illustrated a “hands-free door pull.” Customers who entered did so through a front door that swings open with the touch of an elbow or forearm...

A month after returning too-small yoga pants he had bought his girlfriend, Mark Quinn still hadn’t gotten his money back from Lululemon.

Like other annoyed online shoppers, the 55-year-old executive from Boynton Beach, Fla., called and emailed the company to no avail. “You just couldn’t get through to anybody, it was torture,” Mr. Quinn said, until he finally got through and received his refund.

The chief executive of Juul Labs Inc. has a message for investors: Be patient.

Since K.C. Crosthwaite took the helm of the e-cigarette maker nine months ago, Juul has halted most of its U.S. advertising, cut more than 1,500 jobs, stopped selling sweet and fruity flavors in the U.S. and put the brakes on its international expansion. And he doesn’t plan to get the startup back to growth any time soon.

LONDON—Unilever PLC said it would consolidate its dual British and Dutch corporate structure into a single company based in the U.K., a move it hopes will allow it to more nimbly navigate the challenges posed by the Covid-19 pandemic.

Less than two years ago, Unilever, the maker of Hellmann’s mayonnaise and Dove soap, abandoned a similar restructuring, aimed at merging its two, separately listed British and Dutch operating companies. At the time, Unilever had proposed moving its headquarters to Rotterdam.

Zoom Video Communications Inc. drew fresh questions over its relationship with the Chinese government when it shut down a U.S. human-rights organization’s account shortly after its videoconference on the 1989 Tiananmen Square massacre.

San Francisco-based Humanitarian China said when it tried to access the platform Sunday, it found the account had been closed without notification or explanation from the videoconferencing platform. Zoom quietly reactivated the account Wednesday, after the news organization Axios reported on...

Enrique Marquez stopped advertising his dog-obedience classes on Facebook during the pandemic, and instead started using the platform to live-stream sessions and conduct training via chat.

The European Union plans to file formal antitrust charges against Amazon.com Inc. over the e-commerce company’s treatment of third-party sellers, according to people familiar with the matter.

The charges could be officially filed as early as next week or the week after, one of the people said.

Intel Corp.’s semiconductor production hit a stumbling block in March. A chip plant in Chandler, Ariz., needed work done, but the engineer for the job was stuck in Germany because of trans-Atlantic flight restrictions to combat the spread of the coronavirus.

If Intel couldn’t recalibrate existing machines and install new ones, America’s largest chip maker faced a production slowdown just when demand was surging as personal computers and the cloud became critical to facilitate remote work.
