Stops after one track – KaiserTone Audio Player +HiRes Review

I have been using this great app for 3+ years and really like it. However it suddenly plays only one track at a time. I am not sure if its because of any recent updates. Even if Continuous Playback is enabled it still stops after playing a track. Any thoughts? UPDATE: I found out that the albums/tracks that were transferred using Airdrop were the ones affected. Those transfered using iTunes we playing just fine. Hope a fix will soon be released.
