We have a flow that triggers an approval as part of a managed solution - when the solution is imported into the target environment we get the error: LeanAssessmentsApproval.Run failed: Connection not configured for this service.
As part of fault finding we have imported the solution into one of our other Dev environments as an unmanaged solution and can see that the issue is the flow is showing as 'Not connected'


In this instance, removing the flow and readding it has resolved the problem - however we cannot find a solution that allows us to re-connect the flow in:
a) a managed solution
b) without deleting and re-adding the flow
The managed solution is due to be imported into the target environment by someone that is not familiar with the 'backend' of PowerApps so it's a fair assumption that they cannot be expected to edit/add/remove etc.
Is there a way to import a managed solution whilst maintaining the connection to the flow within a PowerApp or is this a current limitation of Solutions?
