@phirework I’m on Firefox 70.0.1 on Windows 10. I tried on Firefox (not sure of the exact version) on Ubuntu with the same result. I also get the same result with Chrome 78.
I am logged into my account. I tried logging out and recording clips as a guest and they still fail to upload.
If I check the Network tab, I can see that the POST request fails with status code 500 save_clip_error.
