Hello @ahsan.autodesk
Perhaps it's a bit late but I've figured out how to reproduce it! Yay!
The steps to reproduce work on my coworkers computer as well. It is currently still occuring on both of our computers (Macs).
Start with two files - Original File and CAM file let's call them.
Insert Original file into CAM file.
While in the CAM workspace of CAM file, open Original File.
Update Original File.
Go back to CAM file (still in CAM workspace) and open the Data Panel (do not update out of date references).
Right click on CAM file in Data Panel (still not updated!) and choose "Share Link".
The "out of date" message then appears in the CAM workspace!
And it keeps appearing in the CAM space of any file until I quit Fusion.
Then, it lays in wait until I share an out of date file while in the CAM space again.
I share files often - between coworkers and customers - so this is a semi-regular occurance - opening a CAM file that may not be updated and sharing it. I've been getting better about keeping things updated so I've been seeing it less. That's why I noticed right away today when it showed up when I was sharing a file.
Here's a screencast too!
I'm kind of excited I managed to figure it out.
Thanks for your assistance!
