Hi HariJ Thanks for you feedback, glad to know its working as expected for you! Please see responses to your questions below
1. By multiple team pages - do you mean by multiple channels? If yes, then you can go ahead and configure connector to each of the development, customer support team channel etc. and then they all will be notified based on the activity. You can choose to configure connector different for each of the channel. For ex: product team is notified when item is created and sales team is notified when item is updated etc.
2. 'Allow posting messages to multiple channels of same page' - Your message will be posted to every channel where the connector is configured. If the connector is configured for Jira Project X in 3 different channels - All of those channels will receive the update
3. 'Ability to create new channel for each Jira ticket' - This is interesting feedback. Will add to our backlog and will review with the team.
