 ## [Unreleased]
 
 - We fixed an issue that could cause iOS apps to restart repeatedly after an OTA update.
+- We addressed an issue on iOS, where a iOS-system dialogue would pop up during app startup, requesting a password. This was identified as part of Keychain read queries when a one-time keychain migration occurred.
