Issue
Activities that were added to Favorites remain visible in the activity list on the PC even after they have been deleted.
Actual Result
The deleted activity is still displayed in the activity list on the PC.
Clicking or attempting to delete the activity displays the error message: "Unable to load the activity."
The deleted activity does not appear in the mobile app.
Expected Result
Deleted activities should be removed from the activity list on both the PC and mobile app immediately and should not be accessible.
