Trying out he new function, but even if my notification channel is set up correctly when i try to setup the alert, I just cannot save the Alert.
When I try to save the Dashboard I got a message from the Browser along the line of " there are unsaved change"
I do not see any save button on the Alert tab.
Look at the Save Modal dialog - see the “{{ctrl.message.length || 0}} / …” That shouldn’t be there, those are variables that should be replaced with what you are typing. That happened to me to with the Beta too.
I solved it by creating a new dashboard, and rebuilding the panels.
