Elon Musk and Tim Cook have apparently made up following a dustup over the status of Twitter’s iOS app. Musk, who earlier this week, claimed that Apple had “threatened to withhold’ Twitter from the App Store,” said he and Cook had a “good conversation” during a meeting at Apple’s headquarters.

“Among other things, we resolved the misunderstanding about Twitter potentially being removed from the App Store,” Musk wrote. “Tim was clear that Apple never considered doing so.” Musk never said what the original source of Apple’s issue with Twitter’s app was. But Twitter’s former head of trust and safety has stated that Apple had flagged various issues during the app review process in the past.

Of note, Musk’s latest tweets don’t mention if Cook addressed any of Musk’s other recent complaints. In addition to the App Store issue, Musk had also joined the growing ranks of developers to criticize the App Store’s 30 percent “secret tax” on in-app purchases. Musk reportedly delayed the re-launch of Twitter Blue subscriptions in order to avoid the fees, according to the newsletter Platformer.

Musk had also called out Cook for halting much of Apple’s advertising on Twitter, claiming that the iPhone maker had “mostly stopped” ad campaigns on the platform. The company is currently trying to reassure brands amid a broader pullback in advertising from the platform.
