When I use the location sharing feature in Messages (in both iOS 11 and iOS 12) lately, it shows my location with some chinese text saying my location is some sort of spa (my girlfriend translated from Mandarin for me). I get the same text when friends share their location with my via iMessage. It's always this string of Chinese text in the thumbnail of the Apple Maps location with some chinese text regardless of where they are. Attached is an example of what this looks like. This is a message thumbnail from my iMessage transcript when my friend shared his location yesterday. He was not at a Chinese spa. Has anybody else seen this issue?
