My emoji keyboard has disappeared on my Ipad

Hello,

Try resetting iPad's settings in Settings > General > Reset > Reset All Settings. Be certain you do not select Erase All Content and Settings as this will erase all of your information. It is a good idea to perform a backup of your iPad prior to resetting its settings.

Hello,

Have you tried restarting iPad?

Restart your iPhone, iPad, or iPod touch - Apple Support

Hello,

Is Emoji still listed under Settings > General > Keyboard > Keyboards?

You are welcome!
