Beloved dears:
I too suffer from this design sabotage in my
Lollipoop device. This is how I had set up my notification preferences looong ago, to no avail:
Lollipop notification policies are such an unbelievably pile of goddamned arseshyte, I have to admit that, at times, I wish, I REALLY REALLY REAAAALLY WISH the culprits of it would be so arseholely kicked on the arse so awesomely hard that, by the next millenium, they would be yet to land, in a blackhole in a far far away galaxy…

Take care.
Cheers
