Skill id: amzn1.ask.skill.23f31e96-34c6-4027-99d3-57c9c5e360e8. Called My Monthly Calendar.
This skill works only on devices with a rectangular display. It requires linking to a google account. It passed certification and has had no changes since (no changes to the backing lambda etc), so I think the problems I'm getting below are only for me, and not for all users.
I try my skill on my devices; If I try it on one that doesn't have a screen it detects this and gives a speech response explaining to the user that it needs a display. If I try it on a device with a screen I can correctly link to my google account (i get the card prompt in activity. If I try it with a linked account I get a progressive response correctly, however after that the device does nothing. There's also nothing in the Activity listing in the Alexa app. If I look in my cloudwatch logs I can see the request and response worked correctly; no errors were logged, and the correct response was logged. If I test using the "Test" section of ASK it works fine. It appears my devices are having an issue with the APL returned, however I'm not getting any kind of error or anything, the device is just reacting as if the progressive response is all that there should be.
