Dear AgriMike

Good day!!

Apologies for the inconvenience caused and please don’t worry, let’s work together on your concern and move towards a resolution path.

First of all, thank you for the screenshot you provided. We did multiple tests on our end we were not able to reproduce the view as your user described.

This is the view we are able to reproduce.

To test if this issue is related to the user's computer please use a different computer and login to the user's account and try to open the PDF and see if you get the same use as the user describes. If you get the same error Please share a full screenshot.

Thank you for your understanding and wish you have a lovely day.

Have a nice day!

The files are opened in SharePoint from a document library by clicking the filename.

For the user all the other apps have a light background

When the user with the issue logs on to another laptop they still have the same problem. It works OK for the owner of the that laptop.

1. Owner of the laptop opens a PDF in SharePoint and it is OK
2. Switch to private session and the user with the issue logs into SharePoint and opens the same PDF, The issue occurs.

The problem has started to effect more users but very gradually.
