i dont have to test this, because when i create a completly new list and reload the website 5 times it changes from panel to fullscreen.
but when i delete the formatting it also opens in fullscreen.
it also works when i delete the cookies for the sharepoint site, but when i reload its gone again.
Dear @flowa,
Has the UI been updated on your tenant? The Microsoft is slowly releasing new UI for SharePoint Lists, and it currently doesn't support panel view - we're working on making it accessible, but I need to make sure that you have the new UI and it's not some other error.
Can you upload screenshots from your List View UI? Are default forms opening in a panel or in dialog?
We will continue the conversation in ticket SP40857. Please share all the details so we can understand the root cause of the forms behavior on your side.
