Sorry… it appears the original (very empty) post was amended at some point.
The Remember selected tab option should cover this. Keep in mind Plex will store this for each library… so if you switch between Recommended and Library for one of those libraries, Plex will remember the last selection. I’m not aware of an issue where Plex is forgetting the setting.
There’s a feature suggestion asking for an option to remove the Recommended section. Although from what I can see it hasn’t yet seen all that much attention.
