I was trying to integrate my Actions-on-Google assistant app with OAuth 2.0. It wasn't working and I was playing around with the UI flipping switches to find out what would work. When I inactivated the app, I couldn't re-activate it!
The error message is 'Your app must have at least one action to test' (screenshot). But the app is fully functional and I could test it before inactivating. The app code is here for reference.
To be sure that I haven't messed up anything else, I also inactivated another similar project number-genie that I had successfully working and that too cannot be activated again and shows the same message!
How can I reactivate the simulator for testing?
