Unable to load any photos to shared album
Hi there, I have ~3000 photos I need to move from my photostream to a shared album. Im using a 2019 iMac, the latest os, and have tried turning off and on iCloud sharing to no avail. When I did turn it off I was able to upload 1 photo, then I tried to upload the 3000 and none uploaded. I've been trying different things for months and can't manage to upload even 10 photos. I understand the photo upload limits however I have never come close to 1000 photos, 1 is the best I've reached. Any ideas?
