I just had the same problem this last weekend. Not sure what causes itSome times my offline maps in OnX do not work. The map is a little fuzzy and it wont show the boundaries or owner info. I put my phone on airplane mode just to keep it from trying to get service, but that didn't help. Anyone else have this issue?
Thank you.Just a suggestion.....make sure to turn off/shut down the app on your phone first. Then, switch to airplane -mode. After that is settled in, open-up the OnX app again. It seems to me that if it starts trying to connect via cell service, than that's when things go a little wonky. I've been using the app for quite a while and this seems to work for me.
