Is this a new feature

[Sayk1]

Recently I have updated my app and just after updating I couldn't log in with my phone number. Secondly I found out that I can't slide/click the progress bar for repeating/skipping a part of a song. For example, I'm listening to a song and I want to repeat the last 30 sec of the song but the app doesn't allows me to do the same. I have searched on Google and came to know that repeating a song is  a premium feature but does that also include repeating a part of a song? How can I even fix this I have tried everything.
