Hello,
Here's the turn of events.
I have an app with a flow connected to a button. To make things simple, the flow will send out an email. So at this point, everything works and I'm able to send the email with no problem.
But then i want to add a new connection, so that i have permission to send the email with someone else's email connection. So that person is made the co-owner, goes to powerautomate, and changes the connection for that email action to their connection instead of mine.
When that was saved, errors started popping up.
A summary of errors:
1. This error came up when i clicked the button in the application.

cc: Flow failed: {"code":"InvokerConnectionOverrideFailed","message":"Failed to parse invoker connections from trigger 'manual' outputs. Exception: Could not find any valid connection for connection reference name 'shared_office365_2' in APIM tokens header."}
2. When i attempted to remove the flow from the application and add it back, this error came up (while trying to connect the flow back to the button):

cc: Failed during http send request.
3. When I went back to the flow,

cc: There's a problem with the flow's trigger.

cc: Failed to parse invoker connections from trigger 'manual' outputs. Exception: Could not find any valid connection for connection reference name in APIM tokens header.
p.s. the code in the trigger had nothing wrong.
4. In addition to the above, i noticed that a new dynamic content appeared

cc: Parameters: $authentication
For extra information, the only items i "asked from powerapps" are strings and they are stored in a "compose" action.
I would appreciate any help with this issue. Or to be directed to anyone who knows how to fix this issue. Thank you in advance!
