Today I solved these issue (for Levo 2019 and Android)... In the next days I will release a new version.I used to app for a while whilst riding today, but I've noticed a couple of bugs. It only ever shows the power setting as trail. Cycle through modes and stays in trail on the screen (Android).
Also when reduce down to eco via the bike, the power setting stays at trail. Can switch to turbo and get that mode, but not eco.
After that I turned the app off to restore normal riding settings.
