Why can’t I mark more media items as Follow-up?

Each user’s Follow-up list is limited to 100 media items.

When this limit is reached, the application displays a notification indicating that the Follow-up list is full, and additional media items cannot be marked as Follow-up.

To add new Follow-up items, remove the Follow-up mark from media items that have already been reviewed or handled.

The Follow-up feature is designed to help you track items that require future attention, so once an item is completed, it should be removed from the list.
