For me the Android app has been inconsistent, or even regressing. I have a 2017 C-Max Energi Titanium with Sync 3 (v3.0.20204); some of what I observe may be due to the car that I have and its equipment. Unlike several others who post on this forum, I have not upgraded to Sync 3.4 via Cyanlabs. That probably plays into this as well.
Here is how the app is currently working or not working for me:
Home screen: Remote unlock, remote start, and remote lock all appear to work. There is a "My News" box with a "Find a dealer" button. For a while, a charging banner would appear when the car was charging, but I haven't seen that for a while. When charging is complete, messages are appearing in the message center in the account menu from the home screen.
Vehicle screen: shows time since last updated, location, odometer, battery gauge, fuel gauge, vehicle status button, and scheduled start button.
Vehicle screen, status submenu: shows tire pressure warning button and oil life button. These appear to be working.
Vehicle screen, charging submenu: Some time ago, I was able to set value charging at home through charge setting button, but now that capability doesn't appear; only "Departure Times" appears. It reports my current departure times and has a button to add more. However, I only charge at home these days, which might be affecting what this submenu offers. The current state of the charging menu appears to generate the most current discussion in this topic.
Vehicle screen, driving data submenu: Journeys button is present. However, I do not record journeys as I did not find the information helpful when I did.
Service screen: I have not used this up to now. I just enabled vehicle health reports to be sent to me; I will have to see what comes from that.
Map screen: shows the correct location of the car and my smartphone. I haven't used the other features here (fuel, charging, etc.).
Hope this helps.
