@merrimanr I reviewed and tested on full dev. I have the same thought as
@ruffle1986 regarding the cancelling of the subscription. We should add that
line inside the ngOnDestroy lifecycle hook. Besides that, tested on full dev
and everything works as described. This is really great work and will
significantly improve the user experience. +1 once the subscription
cancellation is added.---
