V3.2.1 restores the nice alert message you get when you say "Never" to the request to access your location.
AvTraffic requires access to your location "While Using the App" even if you're not sharing (standby) so it can show you nearby traffic and airports. When you are sharing (active), it shares your location with other users as well.
To change this setting, go to Settings/Privacy/Location Services, select AvTraffic and choose "While Using the App".
