iCloud photo library - wrong video plays
When going into my "videos" album in iCloud photo library, when I click on a video to play the thumbnail gets larger (and still looks correct), but when I click on the play button a different video plays. Sometimes it plays the correct one, sometimes it plays the last one I clicked on (not the current one I clicked on), etc. It feels like the thumbnails are not correct, or the links they take you to are wrong. I have logged out, rebooted my computer. Any suggestions? Just a bug?
