I can confirm that this is still a thing and caused me to die multiple times which could've been avoided because it wouldn't allow me to eat. The LT and RT triggers on Razor Kishi are glitched pressing multiple times instead of once when pressed.
Not sure if Mojang considers this a a serious issue because this has been a thing since like 1.19 its been about a year. I stopped playing minecraft when it first started because I couldn't build, open doors, use menus properly. Came back thought it would be fixed after a month or so but I think it's been close to a year with no signs of a fix.
Mobile Minecraft is probably the second largest community after Java with smart phones and tablets and the fact that we have been unable to use controllers for a year is mind boggling.
I would think Microsoft would have the best coders in the world and the fact that their controller input has been broken for half the users for a year is crazy. I also play lego fortnite mobile and have not experienced any issue so it is a Minecraft thing.
