Hello @MFrizel ,
I use the gestures with the hint lines on bottom, but I think this works without the hints as well... If you swipe left or right along the bottom edge of the screen, it should flip you to your open apps. Hope this helps.
Yes, I am aware that I can have the hints turned on and off. I have been used to swiping left and right to switch between open apps. I like this feature because you can swipe through all of the open apps. Now it doesn't switch swiping from left to right and when I swipe right to left it scrolls through all of the apps and goes to the first one. I had to switch to good lock task changer in the meantime but this only opens the most recently used app and doesn't scroll through all open apps with the left to right swipe.
