Hi, Im just posting this to try and get a senior member to pick up this up.
With the npm module @ionic-native/background-geolocation there has been a bug with this app for a few months now that breaks the the entire plugin, however there is a fix as @ionic-native/background-geolocation@5.0.0-beta.21 , this works however the release versions including the latest @ionic-native/background-geolocation@5.2.0 breaks the plugin, how someone can release a new version of plugin with out running a basic test on a release is beyond me.
The error is
"ERROR in src/app/xxx.ts: error TS2339: Property 'subscribe' does not exist on type 'Promise<any>'."
from .subscribe in the code
this.backgroundGeolocation.configure(config).subscribe((location: BackgroundGeolocationResponse) => {
There are many posts about this issue on github and stackover flow, why this breaking bug has not been sorted out I dont know, it may be that the individual working on this plugin needs a good kick up their arse as anyone new to ionic would be completely confused.
