Have you notice how much smaller the Bitmojis are on latest version of iOS? That’s surely an Apple problem!

It's is up to the people who produce 3rd party apps to make whatever fixes are needed so they work correctly in the most recent version of iOS. Let them know about any problems you see.

Contact the people who make that app. I think it is only for iphone and ipad at present.
