Repack status stuck in Unity Distribution Portal

Trying to repack an APK ready for submission to Samsung app store in the Unity Distribution Portal (via the dashboard)

It has been stuck for hours with the status as a pending repack.

Got a notification saying it failed to repack, but I am unable to download the Samsung APK, trigger a
newly published revision or cancel the repack - its seems to be stuck.

Anybody seen this before or know how to clear it?

Thanks

For anyone who has the same issue:

Not sure what went wrong, but published a new version and it worked OK. Old version is still stuck repacking - but no issue with new version.
