If you have unhidden movies, TV shows, and albums but they are not showing up in your library, there could be a few possible explanations for this issue. Here are some steps you can try to troubleshoot the problem:
Refresh your library: Sometimes, the changes may not reflect immediately. Try refreshing your library by closing and reopening the app or logging out and logging back in.
Check different sections: Make sure to check different sections of your library, such as "Movies," "TV Shows," and "Music" to ensure that you are looking in the right place.
