Maybe I'm being picky but the online documentation doesn't launch from the integrated (CrystalSky plus) controller. It downloads succesfully, but then won't open. I suspect it's missing a pdf viewer, but the controller appears to be too locked down to install acrobat, if that is indeed the problem - anyone else got this or is just me?

I haven't tried but that makes sense, and I really hope they open the damn thing up soon to install other apps.

Its not just you! Exactly same thing here. My thoughts the same...no pdf viewer on the integrated remote/screen

Thank you for your feedback, nickedw. I'll help to report this issue.

I raised this with DJI support today anyway when I confirmed others were having the same issue.
