Hello, i'm trying to accept the job offer, but everytime this error message occurs: "This client's account is on a temporary hold. Once the issue is resolved, you can accept their offer."
What's that and what should i do?
re: "What's that and what should i do?"
It means there is a problem with the client's account.
It's not your problem.
What can you do?
The client knows there is a problem with his account. Once he resolves the problem, you will be able to accept the contract and work on behalf of the client.
What should you do now?
I would do nothing at all.
I'm certainly not going to work for a client without having an official contract in place. Because thre would be no way to get paid. This is not the freelancer's responsibility.
