I'm installing my test app on my development store:
Test your app -> Select Store -> install app -> install unlisted app
On installation, I get:
There’s no page at this address
Check the URL and try again, or use the search bar to find what you need.
However (in the store admin page) when I click on Apps -> <my app icon>, I get to the App URL defined in App setup with no errors.
I believe authentication was working as Allowed redirection URL did not raise any errors, even webhook for app uninstall seems to work.
So what was that "error page" about and how do I stop that from happening?
The error looks just like this one:
Of course, my app has nothing to do with the one mentioned there. FYI I've tried clearing cookies, using latest Chrome.
