Hi guys,

I'm having a problem with submitting the work for the second milestone of a contract I've with a client.

He released the money for the first milestone and funded the second one.

I've tried many different ways but still I'm unable to submit the work.

Does someone know how can I solve this?

Thanks 🙂

P.S. Check attached screenshot

It seems this may be a glitch. However, Clients can approve and release Milestones without you having to Use the Submit button. If you have already done work you can send it to the client via Google Drive and ask him to release the second milestone.

Yep, it is a glitch. I saw couple of topics with same issue today.

Hello, I'm having the same issue. Upwork won't let me Submit Work for Payment. I keep getting an error that says "Submission of milestone failed."

Tested with and without attachment, Chrome and Firefox.

Repeat client, existing contract with previous paid milestones.

Please notify when issue is resolved.

Thank you very much!
