Agenda doesn't update properly when a subject is (un)followed

[derivativeoflog7]

Describe the bug
If the user opens the agenda, then switches to the teaching tab and (un)follows one or more subjects, then switches back to the agenda, the pages that have already been viewed and are cached won't update to reflect the change (sometimes even the refresh button doesn't work)
The same happens with new pages loaded and cached after the change if the user (un)follows other subjects again.
The issue also happens inconsistently, as shown in the video

To Reproduce
Steps to reproduce the behavior:

1. Go to the agenda
2. Go to the teaching tab
3. (Un)follow one or more subjects
4. Return to the agenda and navigate through the pages

Expected behavior
The agenda should reload to reflect the changes, or at least the refresh button should update the available subjects
