I don't really know how to explain the issue. The 'step' (List Rows, Custom Connector, etc.) that's used as a title for the flow checker "error" is entirely irrelevant to its content. The flow has a Power Apps (V2) trigger. The flow is a part of a solution imported into a new environment, and I have to edit it so that I can use the custom connector that is not blocked in the environment.
From what I remember, the error's body is always "You may break your Power Apps triggered flow with the changes on the added connections."
If I click on the error to see which associated step has the issue, it goes to an entirely different step than the one used as the title for the error. If I edit or re-create the step, the error is then labeled with a different step. Any attempt to get rid of the error seems to turn into running in circles. Additionally, the same solution imported into different environments has not encountered this issue when editing the flow.
