@projectsolotv, I’m sorry to have to break this to you, but Alert notifications and message formatting is a totally different animal, with a steep learning curve from Grafana 9.x onward. Lots of people have lost their good messages upon upgrading to, or past v 9.x.
If you are depending on Graf for mission critical notifications, maybe you can downgrade to v 8.x, then look at upgrading much more cautiously in DEV environment, first. IDK if your notifications can be salvaged by downgrading.
I suggest you take a look at this very long thread about the issue – there are many people struggling with getting useful message formats for a lot of platforms (email, slack, Teams, etc.) That is just one thread on the topic – just search in the forums “notification” or “template”. Bottom line, there is a lot of coding just to format your messages.
There appears to be just one guy at Grafana labs who has a handle on how to format messages, and has engaged with specifics help with a lot of people – georgerobinson. That said, he is just one man. 
He’s doing all he can in a not-good situation.
Otherwise, you’re wading through obtuse documentation, and piecing together what you can find in the forums. I can’t sugar-coat it – Graf’s new Alerting is a monster.
