I don't think my last reply sent. But yes I think you're right. I have sent numerous support request emails to DD and they don't seem that helpful. Not even a reply. Now my issue is that i cannot connect to DJI assistant to check the firmware version of my mavic. It just doesn't see the mavic or controller. I just installed the latest Windows version 20 mins ago. I'm almost getting somewhere with PrecisionHawk's PrecisionFlight app, but it is telling me my FW is not supported and that i need to update to the "latest" version (1.3.200) - I wasn't aware another update was out, the GO app hasn't mentioned it. I give up...Then the app is stupid/buggy You should probably send a message to DD and explain the situation.
It seems it can already pause/resume and knows to upload from the next point after what's already been done after battery changes, but my guess is that instead of taking into account that there's a 99 point limit and just upload "start point to start point + 99" they try to upload "everything from start point on" which can lead to >99 and it fails.
It's a piece of cake for them to handle that correctly, and DJI's 99 waypoint limit really isn't a limitation if the app developer does it right.
On another note - I wonder how these guys managed to map 1000km of highway with a Phantom - you can't tell me they did it all in <99 waypoint chunks? Lol.
