Group Sync Playback Function

[goodmangll]

I really enjoy the group sync playback feature, which allows me to watch movies and TV shows in sync with my friends. However, I have encountered some problems while using the group feature on the Windows client.
Thank you for your assistance!

Issue 1: Sometimes, when watching a movie in sync with my friends using the group feature, one of us would automatically exit the group without any notification. On the group page, it still shows that they are in the group, and clicking on "Exit Group" has no effect. The only solution is to restart the client and rejoin the group to restore normal functionality.

Issue 2: When one person in the group drags the progress bar, both parties enter a long waiting period. This waiting period can be quite lengthy. However, if we manually pause and resume playback, it returns to normal.

Your experience with both issue 1 and 2 is pretty common. Unfortunately, Syncplay was created by one person who added the function to Jellyfin and has since abandoned the project. And they didn't leave any documentation to help the remaining devs reverse engineer it. So it has not been updated in quite some time and may not be fixed or updated any time soon.
