Paying customers have been more than patient with this issue, providing logs and repro steps to help Plex engineers diagnose the problem. I’m not sure how others are feeling, but for me the lack of feedback is starting to become very frustrating.
I paid money for this service/app only to have a functioning feature replaced by one that simply does not work, for a lot of people. I know that sync didn’t work for some people, but it worked for me (and many others) for years. I don’t think it’s too much to ask that we be given the option to choose between Sync and Downloads
