When I install my app to a second channel in Teams, the this.onMessage will nto trigger

I have a bot which when installed to a channel will read messages using this.onMessage, if I add another channel to the same team it will also read the messages without installing the bot on that channel.

However if a user installs the bot again, to the second channel which some users do, the second channel will not trigger the onMessage listener except when using the @botname command. I cant log errors anything because it just wont trigger. I feel like the context gets screwed up, all the other listeners fire on other channel

Any help please?
