No emojis in instagram app on iPad with Smart Keyboard Folio (external keyboard)

I have just purchased an iPad Pro 11”, installed the latest iPadOS 17.1.1, I’m getting everything set up and I noticed that I can’t activate the emoji keyboard in instagram. It’s only the instagram app so far that this is a problem in, I can use them fine in notes, mail etc.

I have Emoji set up as one of my languages in ‘Keyboard’

I have tried using the world button + e

I have tried holding down the control key

Doing these last two things allows me to switch between English and any other languages I have on my iPad but not emoji. I removed all other languages to leave only English and Emoji and now there are no options when I try and switch, just English.

I can’t see a way to activate the onscreen keyboard either … I feel like this might be an instagram issue more than an apple one, since it’s only in that app? Can anyone help?
