I saw that the mobile companion app is going away by the end of the month and I cant remember how to transfer my coins and YC from app to the FC account
While you are in the app tap the wallet icon (under the gift icon) to open it. Type in the amount you wish to transfer, click ok and then confirm. That's it.
