Hi there,  I am guessing you signed up to managed payments, as your listings have GPay as a payment option, and this used to be a good indicator of MP Signup.

I also note you have had a few sales,  so I am assuming the problem is with your bank account.  Did you use the micro deposit verification system, and if so did you successfully complete the account verification.

Also is the bank account name identical to your ID document and registered ebay details, and are your ebay and bank account types also match, IE: both personal or both business.
