This is a PSA.
Make sure to watch that your completed challenges XP track at the end. Earlier today, I completed two challenges at the same time, one daily, one weakly worth a total of 400 points. I did not get the XP points. It remained at the 200 XP I already had towards my next level. Resetting the game does not resolve the issue.
If you get this issue, screenshot the screen with the completed challenges and submit a ticket. Or better yet, record the last 30 seconds and submit that with the ticket.
