Update required error while launching FC Mobile

I cannot login to my FC Mobile account, for the first time I am facing this problem, the problem started 2 hours ago or more I do not know why but whenever I login to the game it says login fails.

Screenshots? Error message? What troubleshooting did you carry out?

 I can't open the game

Because lag, I relogin, but when I trying to log in the screen said it needs to update, but I already update the game. I checked it on playstore and there's no update text, so I can't play even I can't log in. I already try the delete and instal the game again but still, the screen is the same, I can't log in. I even tried to restart the phone. But it still the same, I can't even log in.

it happends to me too

Hello the game says I have to update the game so I went to the Google play store but there is no update button? I want this problem to be solved quickly thank you

I started game but it shows update required but my game is already updated so I reinstalled the game but still it is showing the same so I came up here searching on Google AI mode

I just bought the new signature Vincent Kompany, and not even 5 minutes later I tried to open the game. And is telling me to update my game to the latest version on the app store. I open the app store and there’s no update? I even restarted my phone thinking it was a bug. Please let me know is anyone else is experiencing this issue. 

i have just downloaded the app and it is asking to update but i have updated it earlier the screen is frozen at the getting warm up page and not even increasing a bit
