After updating Jellyfin to 10.11.0, the loading times when opening a series increased significantly, especially with series with many seasons and many episodes.
I suspect that something has changed in how the server responds to requests and that Infuse is now requesting information for all episodes and only opens once it has received information for the entire series, including episodes from all seasons. When opening a series, it takes up to 20 seconds, but once it loads, when you open another season, it loads immediately.
I don’t think it’s my Jellyfin server because if I open the same series from the official Jellyfin clients, it loads immediately.
This happens with iPhone, iPad, and Apple TV. I am using Infuse Pro 8.3.
