Fortunately my level of trust with anything new on the Power Platform is near zero. Everything must be tested before I will rely upon the most basic features available. This caution paid off today in that I only wasted about 15 minutes before figuring out the problem.
I was getting the error: The function 'Patch' has some invalid arguments. The specified column X does not exist. The column with the most similar name is X.
The issue? You cannot (currently) Patch() a record from a Collection to Teams Dataverse (but you can to SharePoint, SQL, etc...)
Oddly enough, both work fine connecting to the standard Dataverse (non-Teams).
NOTE: I have a "fix" from MS and will detail below
