I checked your account and it was accepted. The message you're referring to is showing only because you're an exclusive member of the agency. It is by design.
Since you`re an exclusive member of your agency you can work only on projects under the agency.
If you would like to work as an independent freelancer as well, the agency owner will need to change your status to the non-exclusive member first. Thank you.
