Konfiguring aPager PRO

Hey there, :wave:
2 days ago I ordered another Gigaset GS290 and yesterday within 15 min was /e/ installed. TOP!!
Since I have been using more and more open source application and services for months, I had nearly no problems with the migration.
However, 2 apps make me problems. One of the two I have to use! Because I go to the fire department I need the aPager Pro app from Alamos (for alerting). As I’m not really familiar with MicroG yet, I was hoping someone here could help me.

With MicroG I have already deposited my Google account and also at “Accounts” I have deposited a “normal” Google account. Anyway aPager does not detect the specified Google account. When setting up the app, it simply does not appear.

Can someone help me with this or maybe already set up this app yourself?

Any help would be greatly appreciated.

Cheers
:hugs:
