Be glad you don't have the cobi.bike app with the smartphone hub. It came with my new Allant 8s. No useful instructions anywhere. The relevant website just re-states what you see on the screen. No real manual. The worst - no tech support that I can find. Mine is not connecting properly to Komoot. If I plan a route in Komoot, I can't upload it to cobi.bike, because the app says it's offline. On top of this, the map display shows roads with such low contrast, just a thin brown line, that minor roads are very difficult to see.
Who would design such a system, and foist it off on customers for the premium models?
