A new report appears to be "report preview"

I’ve created a report for a run, published it and shared a public link. I did it two times and both times after a while the report becomes “draft” and the link is for a report preview and it’s not public anymore. Moreover, the warning message says, “You are currently previewing a draft of a new report. This draft is private to you. Report previews are a deprecated feature; if you arrived here accidentally, let us know how.”

For detailed information about account and report/run ids, lmk how to send you them privately.
