Having bs would be nice for those downhill shots; but remember the PC brigade’s voice has always been stronger than mobile’s, so it’s not really a surprise. Besides, just re-map your wedges and allow for roll-out.
I am not so sure that PC vs mobile has anything to do with the apparent recent change on mobile. I was not here, but I understand bs was once allowed on the green on PC and WGT removed that option - but did not do so on mobile. I guess they just caught up.
Like a lot of things, WGT decides what is allowed or not allowed and since the two platforms will soon be playing a relatively common base, they appear to be making things more consistent.
