Swiping up from bottom right to go back over, as it used to be, was perfect. Now it's swipe from the side and you risk affecting what's on screen like slider buttons in settings which has already happened.

Swiping up from the left to get recently used apps was perfect. Now I have to try about 10 times at varying speed from left or right of centre up to beyond a certain point on screen which is frankly garbage. It's glitchy as hell and does not work. 

This is a massive etrograde step. You've de-optimised the user experience.

I'm experiencing non-stop frustration having had every Galaxy top spec phone to date. Is this what you want? 

Why on earth have you broken this. It's user experience vandalism. 

Years of this optimal way of navigating through gestures ruined. I want this escalated and a formal response. 

If this isn't reversed by, at a minimum, making it configurable, I'll be going to all major tech influencers with this. 

I've never complained like this before. It is truly atrocious what your developers have done.
