Anybody else had this issue.

I have a media server setup with Plex and Jellyfin and now people here prefer Jellyfin but Plex is available on more devices and my users prefer it.

Now I tried watching several movies on iPhone via Plex app and it kept freezing and I had to exit and start again and half the time it wouldn’t remember where I was. I tried to watch the same movies on Jellyfin, again on iPhone and no issue.

Any thoughts? I did watch a movie at my friends on Plex through Firestick with no issue so not sure if it’s iOS or my home network and Plex or something else.
