Adding a datasource makes testing impossible
Hello!
I've recently found and fell in love with your service.
While experimenting with things, I found that once I add a datasource on the "Data" tab of a page, the app becomes impossible to test. When I try to test, it loads up the testing page and then displays a loading app in the preview window that never finishes.
I have tried in the browser tester and the appery.io tester app on my phone, both yield the same results.
Testing is fine with everything up until the moment I add a service datasource linked to my database.
Anything I can do?
