App doesn't ring when screen is out.

How can I get it to work on my Samsung Galaxy A52s 5G?
The hourly bell works only, when the screen is on.
It worked perfecty on my old Samsung, but I now miss the hourly cuckoo call.
I applied for the Beta-Version, but nothing happend...
Any help is greatly appreciated.

Have you tried contacting the developer of the app?
