Hello, In Oreo I could define a list of apps that must always be put to sleep (i.e. never be allowed to work in the background), as well as a list of apps that must never be put to sleep no matter what (i.e. leave them alone regardless of how much battery they use). In Pie I was able to find out how to define the former, but I can't for the life of me find the latter. What am I missing? Is this option not available anymore? Thank you.
