I'm working with a customer and they today started to experience a problem with the details pane in a document library. When I select a document in the library and try to open i get the following message
I have tried to replicate the error by making a copy of the Library /metadata and everything to a new tenant but I cant seem to replicate the problem.
The only difference I can seem to find is that the tenant that are experiencing the problem has a new feture on the details pane called show/hide collumns beneth the properties.
Has there been a release of new fetures recently? Grabbing for any information I can get.
