I have OnX. It is the gold standard...at least compared to the explore app.
My connected devices are an InReach Mini2 and a 64sx.
My problem is that any offline map that I download does not work. I cannot pinch, zoom or access it in any way. - Even in airplane mode. They are basically frozen in the widest of views.
Initially I thought that it must be a paywall issue...well, seems I've wasted $67 on the explore app maps upgrade.
The app is up to date. I'm on a brand new phone. It is driving up the wall...
