Having used kartaview successfully for a couple of years, I am about to give-up on it. The last time I tried to use it, the images never got uploaded and got lost. I tried again over Easter to capture the same roads. The first attempt to upload seemed to be going well, then stopped. Now when I try again, either: it sits there with zero bytes uploaded, the phone gets hot and the battery level plummets, or the app crashes.
I am not going to try again if I lose this lot of imagery.
