Hi Peter
This is correct behavior.
PilotAware does not provide connectivity to the Internet, it is a HotSpot, and so that is why you get the symbol contning the !
In an older version (July 2017 I think) PilotAware incorrectly advertised itself as a Router, and the connected device thought it could use this as a gateway to access the internet.
Your iPad is now correctlt reporting the 4G access (for internet usage) but all activity on the PilotAware gateway is routed to PilotAware.
This fixes a previous issue that whilst connected to PilotAware, SkyDemon was unable to access its NOTAMS - this will now work correctly whilst using PilotAware
Thx
Lee
