ACR adjustment brush feather and auto mask

HELP!  

I am so hacked off with the new 2021 version of photoshop and ACR I'm also fed up of rolling back acr to 12. something or other I've finally given in and trying to get used to it. As we stand I'm leaning towards getting rid of CC my workflow just to slow now..Anyway will someone please tell me on the adjustment brush in ACR where is the feather control please. Also while I'm here can you tell me where the little tick box for auto mask that used to be under all the adjustment sliders has been hidden. I'm about ready to throw in the towel with Adobe CC. Oh and I use Mac if that makes a difference to any help or response to my questions

Thanks
