Mate10lite smart screen notifications

[Android Central Question]

I've just bought a Huawei Mate10 lite, and then the Huawei smart screen. The screen shows the time, date, TEXT message notifications and footstep count. However I can't see weather, gmail, whatsapp notifications. Any suggestions how to get this set up?
Does changing themes affect notifications? I have my own pics on the home screen wallpaper
