Which Build of MMA (see About)?

I have same or similar problem. I click to play an album and MM scrolls down name of each song but won't play them.

Are you playing a file local on the device or via UPnP?

I have just purchased Media Monkey Pro with lifetime licence and have the pro app on my Samsung S21 ultra phone. When I try to play a track on the phone it just scrolls thro all the tracks on the album with playing the track I wanted. Can someone please advise
Thanks
