SD Version 3.16.3.21673 on Android.
I am using SD with a device that is able to provide GPS/traffic data and working as a mobile internet router at the same time. Due to the unreliable mobile connection during flight the router-part of the device is only online now and then.
Thanks for some more detailed information about the related mechanism behind the SD scenes.

There's lots of different briefing information that SkyDemon attempts to update periodically when it's advised there is an internet connection available by your device. SkyDemon doesn't tell you anywhere that all the different information has been updated, but your device should tell you on its screen if it's using either wifi or 3/4/5g to access the internet.
