I am currently running Version Beta-200409 of Max2Play on a Raspberry Pi 3B+ board with a hifi berry hat. Nothing else runs on this device excepy LMS 7.9. I upgraded to the beta version to try fixing this issue and it did not. The issue is that certain albums from artists are missing. I also tried to rescan my NAS. But it is still the same. When I go to my Windows PC and browse the share, the MP3 files are all there and playable. Any help is greatly appreciated!
