Brilliant! I do get the following error when setting up:

“The URL couldn’t be validated. Response does not match challenge, expected value=”1022642872″, received=”””

The number does change in the error from time to time, though.

Any idea what it could be?

Ah great! It is indeed the one we use as well. Do I have to do anything to make sure these get communicated via Messenger or does it happen automatically?
