Describe the bug:
I logged into Glide this morning to work on my app, then but the app opens on a blank page showing no editor. See below

I tried to clear my cache and log in again, but problem persist.

I use Google Chrome, so tried to open in Safari and Firefox - but still the same

Expected Behaviour:
Open my editor to edit my app

How to replicate:
Not sure, open the editor

Demonstration:

Closing this since Mark said it has been fixed.
