I have recently built a flow the gets all MS Form responses and puts it into a SharePoint List.
After heaps of testing and countless successful flows it all of a sudden decides to make the connection to SharePoint "Unauthorized".

The funny this is it is only intermittent. Most of the time failing but some times running fine.
I have tried the following;
- Deleting and creating a new connection.
- Copying the flows.
I did recently change some the view setting in the list but I'm sure this would not explain this failure.
Oh and I am the owner of the SharePoint site.
I'm a little lost without any information regarding the failure.
Any Ideas?
