Category Gallery Applications have stopped working

[StevenRiggs]

I have two Category Gallery Applications when I try to view them either from inside the Content screen or with their URLs.   The apps worked last week, so what's changed on the backend servers?

For what it's worth, this is happening to all of our Category Gallery Instant Apps as well.  Yesterday, when I cleared my cache it was working again but that doesn't seem to be the same behavior for all users as the issue persists.

I'm having the same problems that others have reported. The Category Gallery external webpage is displaying a blank page. The blank page is replicated across different browsers (firefox, chrome, microsoft). Please assist.

The Category Gallery app is now functioning again. Not sure what the fix was?

I've got the same issue (blank page), I have hundred of such Web Mapping Applications, do I need to rebuild all of them using Instant App? 😞

All minimal gallery web applications we have are opening as a blank page also. I have opened a ticket and escalated it from my support account.

Our Minimal Galleries are now functioning again.  I can also create new ones which we were unable to do previously after the November update.  I'm assuming a hotfix was deployed?

This has been resolved.  Bug fixed
