Yeah...I have a Gen 1 adapter, and I found this to be a really annoying limitation. It makes sense from the company's perspective, since it forces you to have their app installed. And at least up until one of the major iOS releases a few years ago (iOS 8 I think?), it was not possible to definitively disable access to Location data for background apps. So you had to decide whether to allow the app to constantly record your location, or instead to delete the app and not be able to use the adapter.
