I get the "uh-oh not able to calculate long routes" error message every time I start up.
My assumption would be that waze tries to calculate a route to work (are you driving to work?) which is in Finland, but as I'm on vacation in Switzerland at the moment the distance exceeds the maximum.
So maybe it's not really a bug, more a user experience problem, but it is still confusing to get an error message at every start.
