@Mario-Ivancic, I have been riding for three days last weekend, without any issues. It is ot beta just because some users experience problems. I experienced many more problems with my zumo, but I don't call that beta.
regarding your suggestion about auto-save, that is already reality. If the app crashes or gets closed by mistake, at restart it asks you if you want to resume tracking, and also if you want to resume your route from where it left off.
I am seriously questioning if you are using the correct app. Can you post the version number of the app?
