The problem I was having is that after all the reassurance that the new method of getting a screenshot would work, I took the plunge to upgrade to 11, even though I wouldn't be able to revert back to 10.
On my smartphone,none of the methods worked. No matter which navigation method I used, 0,2, or 3 button, could I get the swipe up to reveal the screenshot option on the left. Since I had been using 2 button navigation, I was not familiar with the new icons at the bottom of the screen. After hours of poking around, I found that the method used to get the screenshot
option was not exactly as described in the instructions or the many posts about this issue. Once I realized that the far right icon performed like the swipe up with the 2 button navigation, I saw the light.
Not withstanding the above, why Google would change the screenshot procedure is mystifying. With only one hand useful, pressing 2 is impossible for me. That's the reason I gave up on my laptop. Thanks for reading my rambling post.
