2 weeks ago The on-screen display doesn't necessarily mean the event got sent 'cos the app goes into a polling loop when you have the device displayed.
What you need to look at are the log messages.
You should see something like

There's a lot happening here.
Firstly we receive the incoming API call and determine it's a button press. So far so normal.
Now we try to send an event to Alexa. The code thinks it has a valid access token, so looks up the region it's running in and picks the correct Alexa endpoint. And it sends a message.
Which fails with a 401 error! Oh dear, the access token isn't valid after all.
So now we try again, but with a new access token. We see it attempting to get a new token, which succeeds ("200" response) and we try to send the event report. This time it is accepted ("200" response). And my Alexa told me my Drier had finished.
You'll need to find this in your cloudwatch logs and verify the event was successfully sent.

Alexa routine not being triggering on button press
So i've got a script in my preferred language tcl/tk, and to show that it functions here is the result of getbuttons all parsed into a dictionary:
And here is the result when i use the API to press a button:
and alexa device:
and the reverse:
device:
And my Alexa routine: I have altered the routine multiple ways, this is the latest, while trying to figure this out
I've tried with screen closes and screen opens , but makes no difference.
