Hi @anthonys,
thanks for your patience, we think we’ve got to the bottom of this.
We think it’s because of the size of the app.
If you go to your “look and feel” settings,
turn off Auto Import Services and then try to add google, it should work.
We’ve found that adding the google service, causes all your code to get updated, which then causes the save mechanism to fail.
With Auto Import Services turned off, the code won’t be updated.
We’ll be fixing the underlying issue
and hopefully you’ll now be able to add the Google Service
