As with everyone else, (using android s21 ultra), I can not use mobile deposits. I get the same error that it's unsupported or locked. Like some, I am not close to a branch. In fact I have to drive out of state to get to the closest one. I have no way to cash this check, I've tried the local banks, it is not wrote on a local bank either and now my car payment is late. I don't know what to do. I depend on this feature working.
