I've got a handful of flows as part of my business processes which relocate files submitted via an MS Form to a central location on a sharepoint site.
This includes Sharepoint Copy file and Move File.
About a week or two ago, these flows started to fail and investigating the route cause leads to the same conclusion, that, if there is a pre-existing file with the same name the flow fails. This is despite the flows having "If another file is already there" set to copy/move with a new name which as mentioned had been working fine.
There's nothing to change in the flow and nothing has been changed in the flow. This leads me to believe that Microsoft has made a change somewhere in the Powerautomate system.
This needs to be investigated as it's causing serious workflow issues.
