I am a little bit confused: Since our users have(!) their app data in the app group container we should: not switch to a profile based app group or 2. switch to a profile based app group (and omitting the Team ID prefix, since it is automatically added) ?

Thank you for your reply, we will now implement this method :)

Thank you!

Hello Incogn1to, could you please share which which library you are using to generate the key pair (ES256) that make up the passkey ?

Same for us too !

If have the same question and I hope it is possible that apps with different bundle ids can join the same GroupActifity if the variable activityIdentifier is given the same value. Can someone confirm this?
