What happened to my SOS Web and Android

The SOS screen leads with the one thing that matters most and lists, in order, what really happened: who was texted, whether the server reached anyone, whether someone opened your live map (each viewer counted once; chat-app link previews don’t count), volunteers on the way. Then the four most useful things to do now: call 112, a loud alarm, speak for me, photos.

Cancel a mistaken SOS Web and Android
