Currently, Apple is rolling out iOS Update 17.6 to its iPhone and renders installed and already logged-in RA-App of Master- and RA-Agent unusable. In effect, a login to do identifications is no longer possible. We are aware of the issue and are investigating with high attention steps to solve the issue. A new RA App version might become necessary.
Update 15/08/2024: the root cause could be found and a fix version will be published begining of next week. Workaround: As an alternative, the Android version of the RA App can be used.
Update 20/08/2024: The problem is fixed with RA-App Version 4.3.1. The rollout via iOS AppStore has been started.
