What I’m trying to do: Load my app in the Anvil editor
What I’ve tried and what’s not working: Clicking on it from the app selection page
When I load my app in the app selection page, I get this spinner and it never stops spinning:

Of note, I have recently started using the setup described here (Anvil Docs | Apps in development and production) to separate my development and production apps, and the app that won’t load is the production app (the one that I push to remotely from the development app as described in the above tutorial).
Any changes that I try to make from inside the editor do not take because the app never finishes loading and instead I get a warning that my changes will be discarded if I navigate away from the app in the editor. This is not a huge problem because the point of the production app is that I don’t want to make manual changes from inside the editor, but this problem also prevents me from even seeing the current state of the production app from within the editor, which is not ideal.
Please advise, and thank you!
