Issue description: Some Trainers are unable to close the Weekly Challenge completion pop-up, preventing them from continuing gameplay.
Issue status: 

We have removed the Weekly Challenge completion pop-up that could not be closed.

Affected Trainers have received up to 6,000 Stardust and 20,000 XP as compensation.

Trainers who were forced to exit the Weekly Challenge mid-progress due to this issue will also receive the difference in stardust up to 6000 stardust and 20,000 XP.
We’ll share an update once this compensation has been completed.

We have temporarily disabled the Weekly Challenge feature as we investigate the issue.
