Had similar probs to most, where CloudGPS wouldn't start, but fixed that bit with the the apt get instruction in post #422.

But I can't get my GPS to work within the app. It just refuses to kick in when I start CloudGPS. Works fine in all other apps that require it.
Also I notice the maps refresh is very glitchy. Sometimes the map disappears completely and sometimes I get black artifacts (like graphics corruption accross the screen).
