This is affecting a lot of users. A Mod will pick this up, ask a load of inane questions about confirming you are not using a sub account, what device are you using, can you screenshot the error message. They will then tell you there is no common thread to these faults and promise to update you when they know more. You will then wait along with the rest of us for an update that will never come.
Its not the Mods fault put this issue is being completely mishandled.
