Great app - but very flawed since 2015/16

I have used this app for at least 7 years it I think even longer, and I have always loved this alarm the best!!!
You can bring in your own music and wake up with it. Fantastic! So far.

And then something happened, maybe towards the end of 2015 or beginning 2016 - and since then the app either doesnt wake me at all or goes on background alarm which just makes the birds sing instead of starting music. And for me the birds just make me sleep even better.

Initially, like most other users who describe this problem on here, I thought it was a user problem. But its not. I double check, I start playing a song from the playlist before finishing the setup (otherwise the music will not start ever) - and still it doesnt work half the time.

I am very reluctant to let this alarm app go as I have loved it for so long but now its time.
Like another user said: "my alarm app has a flaw" is not a good excuse for sleeping in. At least not in the real world.
Very disappointed. I guess the app creators have moved on to a remote island with their wealth from the app sales...

Dumm and dummer about Alarm Clock Pro, v1.13.1
