On a fully updated Windows 10 machine with google drive file stream, the latest version of sumatrapdf doesn’t detect modified documents on the google drive and reload them automatically.
My work flow is to keep my latex files on my google drive on my local machine and edit them there. In this situation, the pdf file generated by latex is also on the google drive. Sumatra has no trouble rendering the pdf, but, since I moved to the google drive, sumatra no longer notices changes. I now have to hit the ‘r’ key to get the reload. Don’t get me wrong, it’s still waaayyyy better than the alternatives, but I wanted to let developers know in case there’s an easy fix.
I have also confirmed that if I do this on my local drive, non google drive, that the auto reload still works. It’s definitely something to do with the pdf being on the google drive. My guess is that it’s actually google’s fault, possibly not correctly updating timestamp information, but maybe not, or maybe there’s a workaround?
Thanks for a great pdf viewer!
