We have a Sharepoint 2019 on premise enviroment.
The following behaviour is with MS Edge on a document library:
I have installed a new document library with different content types.
If I try to click "NEW" to add a new dokument from a template, then a Dokument called "document1" is created , but without any extensions.
If I switch to classic sharepoint, everything works as expexted.
And also with IE11 it works fine.
Any suggestions ?
P.S. These discussion is also in Edge:
