Is there a restriction with google apps accounts to test actions in inbox with schema? I tried the example but no buttons showed in inbox. The app was created with a google apps account in appengine.
The received mail is :

Google apps accounts seem to not work for the testing purpose. Using the apps script the test did not work for me logged in with my apps account (mail with different domain than gmail.com). The same script worked with a "normal" google account with the domain gmail.com. Interestingly (automatic) forwarding of the mail from the gmail.com account to the google apps account showed the action button in the google apps account too. So it seems, that in general the feature itself already works in google apps like in normal google accounts, with the exception that the "send mail to yourself for testing"-feature does only work for gmail.com accounts.
As per the warning at the top of the page, the Review Action is currently not supported in Gmail. We expect it to roll out in the next month.
