Alright,
For now I don’t have anything actionable for you.
This player had the same problem: Weekly bounties and challenges not reseting, but dailies do but it corrected itself there eventually.
I’m afraid you will have to wait for a bit to see in a few days if replenishment has started again.
If you can submit your files here according to How to Properly Report Bugs! I can let Moon know about your problem as well
