iPhone 14 won’t send Bitmoji in FB Instant Messenger

My Bitmoji personal avatar stickers suddenly stopped working in Facebook Instant Messenger IPhone app on my IPhone 14 about 30 days ago.

I have tried all of the suggested fixes so far. Deleted and reinstalled both Bitmoji and I’m app. I toggled off/on the controls in Settings, and restarted the IPhone.

Nothing works. Help?
