I ended my membership on August 24, 2017 so that I can start the membership taking out on the first of the month and so far every day I log in to do daily quests I get only premium area assignments. I don't know if there is a way for it to be fixed when someone needs to cancel a membership for them to still be able to do daily quests?
The area it sends you to is based on level, you will just have to check every day to see if you have access to the area it is asking for, this is the way it was designed, it is not broken!
