It sounds like you may also be using an external GPS puck with software to split your GPS signal so you can share it amongst several apps. Your iPhone is using its built in location services to currently display your location. This cannot be shared among other apps. It’s only for use on your iPhone. If your Verizon signal drops out for a minute or two your SN location will be affected by that and will display your last known location.
If I’ve made some incorrect assumptions about you using a GPS puck let me know. If not please advise me of all of the apps you’re using along with that setup and if it’s being used on a Windows laptop or whatever you have besides your iPhone. In other words: what OS is your laptop, what program splits your GPS signal, what streaming app are using, what brand of puck do you use, etc.
