I have no resource packs enabled
Affects 1.19.21
Affects 1.19.20
Still affects 1.19.10
This bug has been incorrectly flagged as Resolved. This glitch still occurs and has not been fixed, I'm sure that most people haven't seen this page so they won't know the work-around for the bug.
Ah, I see, I was signed in. My apologies for being a bit harsh there
Can confirm, I also have this issue. I'm running OS X El Capitan on a mid 2009 Macbook Pro.
This issue still affects the newest version, 1.19.0.
I just checked to see if this is still an issue, and the button doesn't even exist anymore, it's been removed?
I have added the version 1.17.10 in the affected versions list. I tested it again and it's still broken
It seems to be fixed for me now
I no longer play Minecraft on Kindle Fire (I recently purchased an iPad and I now use that instead) so I am unsure.
