Cloud account switch - no file sync

I needed to switch my mixo cloud account to a different one. I use google cloud and needed to switch to a different google cloud account.

I can't get it to re-upload all the tracks etc, though.

The cloud info in the settings shows the new google email address I used to login to, but it shows that the tracks have been uploaded. When I check the google drive, there is no data, though. And my ios player can't find them either.

I already tried the Re-Sync This Library tool, but it doesn't seem to do anything.

How do I resolve this issue?
