I tried loging in today and the app says, miner suspended.
What could be done about it?

Did it give you an option to verify you are a legitimate user?

Mine did that 2 days back, actually I think mine said BLOCKED, but it gave me an option to verify I’m real.

It was just a bunch of Captcha images to show human user.

Try see if you get this verification Captcha. If none appears try update the app which mine also very recently updated.

If no auto update, go direct to the play store and see if there’s an update available.

If none of this works you might need to contact support and open a ticket.

Thank you. I have long resolved the issue.
