iOS 27.2 beta: Zoom app keeps re-asking for the meeting passcode

When I join a meeting from the Zoom iOS app by entering a meeting ID and then the correct passcode, the app returns to the passcode prompt with no error. If I close the dialog, tapping anywhere in the app brings the prompt back.

Setup: iPad Air (M3) and iPhone 17, both on iOS/iPadOS 27.2 beta. Zoom app version 7.2.1 (38756).

What I’ve tried: deleting and reinstalling the app, a hard reset, signed in and signed out, Wi-Fi and cellular, iCloud Private Relay off. The behavior is the same every time.

What works:

• Joining zoom.us/test, which has no passcode
• Tapping a join link with the passcode embedded
• The web client at app.zoom.us/wc/<meeting ID>/join, with the passcode entered there
• The Mac desktop app

So the failing step seems to be manual passcode entry in the iOS app. Is anyone else on a 27.x beta seeing this? I’ve also filed a report with Apple.
