I removed "Meta" from my phone and reinstalled it. I have a friend who is in the same situation. After trying it, it was effective and his problem was solved. You can give it a try.
Yes, having two CCS accounts on the same device is risky.
If there is a problem with your computer's Meta, please try "Start"-->Settings-->Applications-->find "Meta"-->Remove. After shutting down for 2 minutes, re-download and install Meta.
Did you? Oh congratulations! I am so glad for you. I am sure at one point we will get to grips with this game and become the "Amazing Diamond Diaries hunters" Lim tells us we are. ๐๐คฃ
