App notification volume is ringtone volume

Hello,

I'm using the shelly app (Android, Version 5.24.4/7e325dc) on a Samsung Galaxy S20 FE (Android-Version 13) and have the following problem.

Normally in android there are different volumes for notifications an incoming calls. But wenn i receive a notification from the shelly app through a scene the phone is ringing with the correct notification sound but with the wrong volume from the normal ringtone?

I checked all notification settings and they seem to be correct (see attached screenshots).

Is this a bug or is there something wrong with my app/smartphone/cloud? I already tried reinstalling the app and restarting my phone but the behavior is the same..

Kind regards

Andreas

Update:

I swaped to the new Shelly Smart Control App (Android, Version 1.15.1/16874a7) and the problem is still the same as described above.
