Users being prompted for sign in every time they open a PDF from SharePoint

Question

I have a few users in my organization who are experiencing some odd behaviour with Adobe Acrobat Online. When opening a PDF from a SharePoint library, it will ask them to sign in and authenticate every time. It doesn't seem to matter whether they select "stay signed in" or not. Every time they open a pdf, it will prompt for sign in and MFA. So far, I've noticed that it affects users on Chrome but doesn't seem to affect Microsoft Edge. I've tried clearing the browser cached files, credentials etc but no change. If they right click the file and open in the desktop app, it's okay. Just when opening in the browser. Has anyone come across anything like this before?

Hi HughieGilchrist,

Thank you for reaching out.

Please let us know how they are opening the PDF from Sharepoint. It would be helpful if you could share the screen recording of the workflow.

Share the screenshot of the sign-in message they receive when opening the PDF. Have you made any recent changes to the browser that may have affected this behavior? Share the Browser version currently in use.

Thanks,

Meenakshi
