Hi all. I renewed my membership, got a confirmation E-mail, and followed the link in it to check the status. It says "enrollment complete." But if I log into the developer portal, it says "membership expired." There is no chat option for support, only a form for E-mail. The response time quoted is up to two days. Meanwhile, I can't implement some critical features in an app I'm building, because they require an active developer account. Not cool, Apple. Anybody else experience this?

I have a project that has been building fine up until recently, when I started seeing spurious errors flagged in the editor on lines that were correct... and when the build was reported as successful and the app ran. The lines were often flagged twice for the same "error," and selecting the suggested "fix" produced syntactically incorrect lines because Xcode replaced the wrong characters. Now the builds are actually failing, on correct lines and preprocessing failures (allegedly missing header files that have never been missing before, with no project changes). Also there's a lot of Could not read serialized diagnostics file: error("Invalid diagnostics signature") reported in the build output, although that's categorized as a warning. Cleaning and deleting DerivedData has no effect. I'm not using CocoaPods or Swift packages, which you see cited in a lot of reports about this. Has anyone found a workaround?
