What and where can I find quick setting mode
a message came saying reset to play , but can’t find it ?
Quick setting mode????

Still no luck in getting to change battery settings
Are you saying you can't find the 'play' button: 
When you press the setting butt on the top right of the screen you show it brings up the battery battery charge and discharge options , but these are all greyed out and a message as shown above is displayed
I have tied switching on and off the quick setting mode but to no avail snd also uninstall app and reinstall still no response!!!!
I can change settings on my laptop with no problem , but on app it’s so much easier when working !
It was working all fine till last week !

the suggestion from cluelesscris
is that you have used one of the quick settings in the app and now need to cancel that by pressing the green play symbol.
do you have that or do you see a green pause button?
