Retool Preview release always blank (for unpublished releases)

I am having an issue, when I create a release of my current app... I am unable to preview it myself also when I share the preview link with others it turns up blank. the only way preview works for me currently is when I publish the release.

I have tried the preview on Firefox, Chrome and edge
