Android 7.0.
I also have latest version of the app installed on iPad Air 2 with iOS 11.4. As per your earlier note, sync still does not work on iOS either, the D/D setting info does NOT list on/off time, and the advance/delay is +-90, in 15 minute increments. A rather large disconnect from the android app.
To see history records, I use an iPhone 5 running iOS 10.
