I don't know if this belongs in the iOS, inReach, or in the Earthmate forum so I'm posting it on here instead.
I have an inReach SE firmware v2.16, an iPhone 8 iOS 11.3.1 and the latest Earthmate version. Whenever I text using my inReach SE my position is shown to whomever I am texting, but when I text using my iPhone my position isn't shown. In Earthmates Options setting, Messages is set to Include Location. Is there any other setting that I am missing that I need to enable/disable in order for my position to be shown when I text with my iPhone instead of my inReach?
