I’ve had 100k+ MAU since at least a year ago (analytics do not go back any further) and yet I just now received the Sparkletime Crown. I’ve had 1m+ MAU in December of last year, but no crown has been given.
I assume that it’s just extremely delayed for some reason.
I’ve emailed devawards@roblox.com as they instruct you to when you email support about a devaward. I did this on July 15th, and I have yet to receive a response.
