I'm having the same issue now. Were you able to find a solution?

What software are you using? What version NUMBER?

What is your operating system? What version NUMBER?

I have previously shared edits to Discover with no issues. Recently, I kept getting the following error when trying to share my latest edit to Discover. I tried closing and reopening the app but no luck. Any idea why this is occuring?

Why is this posted in Lightroom Classic? Is this not a Lightroom Ecosystem (Cloud-based) issue?

[DL_Phototography]

I'm seeing that this is posted in Lightroom Ecosystem (Cloud-based) and not Lightroom Classic.

My initial post about this got merged here. When I reported the bug
directly from the app it sent me to the cloud based threads.

This is typically a symptom where the edits have not completed syncing with the Adobe Cloud prior to your submission.  Are you fully synced before making the attempt to post to Discover?  Do you currently have any sync issues?
