Null's brawl not starting up for 2 months

So, 2 months ago i got this error while playing.
Updated the app, restarted device, unistalled and installed app, and nothing. Can somebody help?

Did you read text in the tab?

Well, it’s in portuguese for him, maybe he didn’t get it (I guess)

Clean app data

Alredy did it 10 times, same error.

Probably you delete the cache, not an app data…

If I’m wrong, reinstall an app.

Ok, i will try re-installing the app.

Let me know if something going wrong.
