On the bad side Guthooks appears to have torched their entire user base with the last update so people can’t access their maps other than the one they currently have open.
Fixes aren’t working.
On the other hand they have a neat feature for following friends and family on the trail.

How to Send a Check-In in the Guthook Guides App
IF I’M FOLLOWING SOMEONE AND I DON’T PURCHASE THE FULL TRAIL GUIDE, WHAT CAN I SEE?
If you’re following a hiker and choose not to purchase the full trail guide for their trail, you will be able to see any location and check-in that they share, no matter where it is, but you will only be able to see the line of the trail and the waypoints for the demo section or any sections you have purchased.
Update
I just deleted the app and restored from the App Store. That solved everything.
It even kept all the data from when I tracked where we were on the AT. Neat.
