I submitted a ticket as well after getting the Back Up badge, further showing I didn’t get my Notice.
I got a lovely and polite response stating that they are not awarding missing merits or rewards. It also stated that if I felt this was a bug to post here.
As such, I agree that not providing the rewards from a weekly target is a bug. The rewards are the primary reason most people do the weekly, so if this bug can be addressed, it would be greatly appreciated.
Thank you.
