I confirm that SD doesn't appear in the list of apps where you can select "background app refresh" (in iOS Settings).
I did however some more testing today, and can reconfirm the loss of GPS data connection (and subsequent reverting to planning mode) when locking the iPad (using the hardware button on the fame of the iPad).
- When locking the device (using the hardware button on the frame of the iPad), it will *immediately* lose connection (even if only locked for only 5 sec).
- When I open again the iPad, SD is “Looking for GPS Data” for a few seconds, then reverts to planning mode and displays an error msg (“…no GPS data received for some time…”).
- However, GPS data *is* available, and SD can immediate be put back into “Go Flying” mode. The green banner “looking for GPS data” appears for a fraction of a second, and it will reliably re-connect to PAW.
I can no longer reproduce the same problem just by toggling between apps, even is SD is in the background for > 5 min.
PAW Support reckons that this needs to be fixed on SD's side.
