@6b6561: Thanks to your answer I finally got my lazy ass in gear and set up MiXplorer's FTP server which I should have done long ago. Way smoother and way faster than GD. Thanks for that! It didn't actually solve the problem. I still saw the “Unknown artist”/"Unknown album" after transfering over FTP. The full rescan did the trick though. @andrewilley: Thanks for answering my question. Next time I transfer files I try to disable auto scan and see what happens.

I use Tag&Rename on my pc to get my tags in order. I transfer my music files to my phone via Google Drive. Recently near all my transferred files have started to show “Unknown artist”/"Unknown album" in the list view. Sometimes it’s all of the files in an album and sometimes some of the files. When I open info/tags on an “unknown artist” file all the tags are there. I then have to push Edit Tags and then Save and everything is good. This I have to do with all files with unknown artist. What can cause this behaviour? My phone is Xiaomi Redmi Note 7 stock rom and I’m on latest Poweramp.
