I’ve been trying to neaten up my albums by deleting duplicates. Unfortunately, when I do that it deletes the whole album and any other dups, including the original. Two questions:
Deleting an album is a permanent deletion (i.e. you’ll have to redownload the files if you want them again), but it should only delete the version you’re looking at.
Can you share a screenshot of Settings > Storage? It’s possible that some duplicates are not actually file duplicates but are files being watched twice, so they’re imported twice, even though there is technically only one file. This screenshot will help us confirm if this might be the case.
