I added an attachment showing that this bug still happens in v1.16.210.
in the video the keyboard wont show up because of Samsung reasons
It actually occurs when your keyboard comes up. I tested it typing, then I tested it using "Autocomplete Addon"
It switched while I manually type it, but doesn't switch when I used the Autocomplete to use the same command.
This seems to only be affecting mobile editions as I seen on YouTubers' videos that it works fine on Windows 10. I don't know about Xbox One, but it just doesn't work on mobile.
It is fixed.
I was gonna attach a video to it but it was too large (25/10 MB)
Minecon skins*
Affects v1.18.12. I have attached screenshots for jungle generation between 2019 and now, and you can see the lack of bushes in the 2022 jungle generation.
