I'm unable to successfully update/publish any apps in our tenant. Everything behaves as usual, but after clicking update, the "Publishing app" in progress indicator just spins.. I've attempted in multiple browsers and tested from different IPs with different accounts but no success. I am able to see changes I make to reports in the app after updating, but end users are not. Strangely, end users have indicated that these changesare visible for a momentbut quickly revert back to their pre-update state. I had the end users try different browsers and clear caches, etc,. but same results.
Example screenshot below shows the first minute after clicking 'Update', but it's still "Publishing" as I post this over an hour later.
