I found Discogs OK for a while then I bought a few things, got scammed a couple of times which Paypal sorted. Got refunded a couple of times as sellers had sold stock on other platforms and not removed it from Discogs. Left negative feedback for those sellers which Discogs removed. Noticed after a short while the huge amount of duplicate listings under barcode / catalogue numbers.App was pretty rubbish, continually get logged out and then what topped it for me was being unable to access the app at home through my WiFi. I either had to use a VPN or turn WiFi off and use mobile data. Raised a support ticket and got no response.I did list a few items that weren't in their database (new titles only) only to see duplicate listings the following day of same item so that became a waste of time too!Be happy with your collection in front of you rather than on an app or pc is my advice!
