I asked this question some time ago and I had a problems starting the app when I’m not connected to the net. I’m using 6.0.3-beta.14. on an Android phone.
I clear traps in a remote location where there’s no network coverage and today when I was trying to use the app I couldn’t get it start up. I think I saw a message on the screen about it trying to authenticate but it flashed up and was gone too quickly to be sure and then the app shuts down so I had to try again. Same thing happened several times.
I put the phone into Flight Mode as that seems to have helped in the past but then I got the map pictures for the area but no lines or traps marked on it. All of this is quite unhelpful.
As soon as I get back to “civilization” and turn Flight Mode off it all comes good. It seems that there’s more testing need for off grid usage. I’m happy to help with that.
