Can a new version be made like 5.600?

I’ve used 5.6 for years, and now use an old phone just because 5.6 has 1 minute poll intervals and the ability to specify a notification sound. These are essential to me, and 5.6 does not work on modern versions of Android.

So could an upcoming version include these former features? I would be happy to donate.

Thank you

You can still specify a notification sound (have a look at the other threads in this forum). 1-minute polling cannot be added because of Android requirements (there is a more detailed explanation in a thread here, too).
