The Coinbase team has manually disabled my account without explanation -- I'm skeptical that removing / re-adding my bank account would re-enable my trading and transferring between coinbase / coinbase pro. I'm also not sure that I'd even be able to complete those actions given that things are disabled for me right now.
Are you able to login to your account? If so, go to Settings > Linked Account. Remove your bank account, then add it again.
Had a similar problem, similar reaction to yours. I tried this and it fixed my problem instantly after 2 months watching at the market crashing... I saw a post on Reddit explaining that this trick was the only thing that worked.
