Works in theater mode only when entering theater mode from a post where the tags were created

[ErroneousFatality]

Example: If you view the picture(s) inside a post (https://www.facebook.com/USERNAME/posts/POST_ID) and there they get their tags created and added, and then click on any of them to view them in theater mode, it will work properly. Entering theater mode and viewing pictures in it rarely works otherwise; like viewing a picture from the news feed or profile timeline.

The biggest problem with this is that you can't go through pictures in an album or sequence and see the tags.
