We have a few users who are running into a bug with the latest versions of Confluence Cloud and Jira Cloud apps for iOS. They're also on the latest version of iOS.
When they are prompted to sign in, they'll enter their email, and are redirected to the Microsoft iDP to key in their password. However, the on screen keyboard does not pop up for them to enter their passwords.
Rebooting their devices does not fix the issue. The only workaround that works is to uninstall and reinstall the apps.
