Hello Usually transactions can take up to 15 minutes to be processed and the perk should be successfully delivered by then. If you have allowed over 30 minutes for the rank to be updated and that still has not happened, you should check out this thread on donation issue tickets. Have a great day!
If you have any other questions, don't hesitate to create another thread or PM me on Discord and I'll gladly help you. Question Answered | Thread Locked
