I have a data source of a SharePoint list. This was working fine, but it has now stopped loading data. If I try to manually refresh the data source it just spins 'Refreshing' infinitely, I also have the breadcrumbs across the top as if something is loading, these never go. I have a gallery showing items from the list, this is no longer displaying any items.
Any ideas? This issue seems to be affecting multiple apps in my environment. Seems the connection to SharePoint is borked in some way. I can manually browse to my list just fine in SharePoint.
I have also tried creating a brand new blank app, adding a connection to SharePoint, then setting up a gallery pointed to it and can reproduce the same issue.
