Hello Everyone,
Recently a few of my clients had reported that their PDF attachment preview on the Timeline in Dynamics 365 Model-Driven App had stopped displaying. Instead of displaying the preview, it would flicker once and show a blank space instead. Searching online returned methods that didn’t work, but after some persistence I was able to find a fix.
To fix the PDF Attachment Preview not working and showing a white space in Chrome, do the following:
Open up Chrome Flags by going to this url: chrome://flags/#pdf-oopif
2. Set the 'OOPIF for PDF Viewer' to 'Disabled'.
3. Click 'Relaunch' in the bottom corner
Now Chrome should automatically restart and the timeline preview for PDF documents should now be working.
Until next time…
Jeremy
