Thanks for reporting this @wgehalo, it looks like it could be related to this issue report on the api we use, but I'll check it out.

Same issue. It looks like it's because of the API changes Facebook made recently to move messenger to using MQTT (a type of messaging protocol like WebSockets).

I had a look at the issues in the facebook-chat-api repo as @tomquirk linked and found the library was depreciating its api.listen method in favour of api.listenMqtt (see issue #786 in facebook-chat-api). The change looks to be a drop-in replacement, so it looks like all we'll need to do is change the line in Messer where this API is being used.

I did some testing locally to try this. The api.listen method is used in the messen library on line 139. After changing this line to api.listenMqtt, it looked like incoming messages were being displayed properly.
