Server Version#: Version 1.32.4.7195
After the latest app update, whenever I click on “Collections” from app.plex.tv, it instead just takes me back to my library despite the UI showing that I should be on the Collections page. On my players, I can get to the Collections section just fine, but can’t do things like change a Collection cover image since I need to do that from the app.plex.tv site.
Go to the plex web settings, You may have to hit show advanced. the under Debug settings, hit the “restore defaults” button. This will only reset plex web not your server settings. It will make you re-pin the libraries/sources you want.
