Apple App Clip Advance Experience Cannot Submit

Getting error "App clip experience could not be sent to Apple." on submit of app clip advance experience?

I am also getting this error. I have submitted 10 or so previously, without issue. The error doesn't explain what or how things went wrong just that you can try again but do not refresh the page. Is there any way to get clarification?

Same issue when trying to edit App Clip details during release phase. Any ideas? The problem been persisting for few days.
