This is really a question to Tim.
I was trying to save a waypoint file to "the Cloud" and found the file was too large.
Please could you advise what the maximum file size is, and then I will reduce mine to that.

When I click on OpenFileFromCloud on the PC, it just shows nothing there, even though I can see it from a Win7 PC and on my android device. Similarly for Waypoints. In short, the cloud is not visible to the Win8 PC. I can access charts and things though no problem. It is just cloud stuff that is not visible. It is not in offline mode.

Ah ha. I cracked it. I had to Logout from the setup menu, then log in again and it all started working. Great. Now I can get on and finish planning the RoundBriatainRally flight!
