When I went into my "Connector Manager" (as I call it) I could see several identical connectors.
For instance I had 3 Outlook connectors to my work email (as well as 2 Excel, and 2 Sharepoint).
I tried to create a "new connector" and chose outlook again... and instead of getting a notice that the "connection is already active" I could add 3 new Outlook connectors to my work email... (and deleted one old)... so now I have 5.
It feels like there should be one with all apps and flows... and not several with a few flows & apps each.
I can also add that I have several duplicates of connected flows and apps in the old connectors, of which several are deleted once. The two red once below can be found in one of my original Outlook connectors and this flow was deleted earlier today.
