Basemaps not loading

Basemaps are not loading and we’re just getting to the spring hiking season! Unusable until this is fixed.

Ahh, just clicked on support link - takes you to a website for a totally different app. Looks like they’re not actually seriously updating this app anymore.

Now Worthless!

I updated the app today & now it quickly closes as soon as I tap to attempt opening it! What was previously a beautiful, informative app is now completely worthless - even after deleting & trying to re-install it.
