My subscription is up to date, my InReach is updated to the latest version, but when I try to send a test message (or a regular message) it tries for about ten minutes and then an exclamation point alternates with the send/receive arrow. I learned that this exclamation point means "Unable to send/receive data" and it is a cloudless night with plenty of sky. What else can I do to figure this out? I'm trying to head into the backcountry tomorrow so if anyone by any chance can help me out I would really appreciate it!
