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.
