Hello,
We've noticed some possible issues with your contract with ***.
While we take a closer look, we'll need to put your contract on hold temporarily.
Please hold off on working on this contract until we give you the all clear. I know these holds are frustrating, but they are essential for the safety of your account and the marketplace. We're doing all we can to clear things up quickly.
Our apologies for the inconvenience. This is a big deal to us too, and we'll do all we can to get you back working on Upwork as soon as possible.
Regards,
Upwork Customer Support
