 Description   

The Toggle Flip-Flop illustrated in the original Minecraft Mojang Redstone Handbook on pages 34 and 35 dos not work for iOS, Android, Windows Phone, Amazon Kindle Fire, and Windows 10. This is not outdated information because the same redstone system (on pages 34 & 35) works in Xbox One, Xbox 360, PlayStation 4, PlayStation 3, PlayStation Vita, Wii U, Windows, Mac, And Linux. That is 65% of all versions according to minecraft.net - Home.

I'm going to close this as Works As Intended because as they are at the moment sticky pistons cannot become 'unsticky' with a short pulse.

You might find the comments of MCPE-14851 useful as that ticket relates to sticky pistons leaving behind a block after a 1 tick pulse.

Ah, I see. Okay, this is not using quasi-connectivity, but what it is using is the faster piston timing in the Java edition. MCPE pistons take a slightly longer time to extend/retract, and therefore sticky pistons are unable to leave blocks behind like in the Java edition. I am not entirely sure whether or not the different piston timings are intended or not. This would be up to the MCPE devs to decide.

Please show a screenshot of the setup that you believe is not working properly.

That toggle-flip-flop design uses quasi-connectivity, which is a bug in every edition except MCPE. This has already been brought up before on the bugtracker and the MCPE devs have decided not to implement this bug because it is not intuitive and breaks exisiting redstone logic rules. So this issue can be closed because it is works as intended. (And honestly, it was foolish of Mojang to not fix the bug on the Java edition last time they considered it. That time they sacrificed consistency and logic within redstone in order to please the community at the time. But not this time. This time, the MCPE devs are keeping the code clean and intuitive.)
