This one has been driving me crazy, so thought I would throw it out there to see if anyone had any guidance or ideas.

There are many ways in which you can @ mention someone from a flow (see the myriad of ways documented here). Depending on if you want to mention a person, a channel, or a tag, there are different methods. For my particular use case, I'm mentioning a channel and a user in the post, so I'm using the Invoke an HTTP request using Azure AD action. This allows you to use the MS graph API to post the message to the channel and do all your mentions in one fell swoop.

To do this, you use the team ID and the channel ID to build the URL of your request. So basically https://graph.microsoft.com/v1.0/teams/TEAMID/channels/CHANNELID/messages. For channel ID, it typically looks like the following: xxx@thread.tacv2. However, if the team was created awhile ago, it will look like this: xxx@thread.skype. My flow works perfectly when I set it up to run on my test team (which has the thread.tacv2 channel ID format), but when I set it up to run to another team (that has the thread.skype channel ID format), I get Action 'Invoke_an_HTTP_request' failed: NotFound error with the flow. Things I've tried:

Doublechecked all the ID's. They are correct.
Just changed the thread.skype channel ID to be a tacv2 one, didn't work.
Tried changing from v1.0 of the graph API to the beta one, didn't work.
Tried the other methods. They work with user mentions, but I still can't do the channel mention that I can with the HTTP request action.

I'm not sure the thread.skype/tacv2 is the issue, but that's the only difference between the two Teams that I can find where there is a difference. Outside of creating a new team (not an option, the existing departmental team has legacy information that we would not want to lose), can anyone think of a way around this? Or am I missing something in trying to pinpoint the cause of the problem? My eternal gratitude to the kind person that can fix this.

Edit to add http request:
