Hey everyone, I'm using a normal flow to save/update some data into SharePoint and call a custom connector to proceed with my process. Nevertheless, I figured out some problem as soon as I insert the flow (or any flow with a SharePoint Connection) to a Power App. When I insert the flow into the app, the flow itself can't be open by the new designer anymore. The error says it's because of using connections instead of connection references, which is not the case, because I'm in a solution and check it several times. Even when I remove the flow from the app, it still seems broken. In general, it should be okay to use the old designer, but the problem is, that I want to send some PDF content bytes as base64, but when I add the logic to the flow, it will be removed after I save it.
So yeah, there must be some issue in the connection between the app and the flow.
Please, can anybody help me here?
P.S. The URL always throws this parameter, as soon as I open the flow: "?v3=false&reason=fromV3"
