Converting Procreate animations into compatible live wallpapers for iPhone Lock Screen and Home Screen

I have created a short 1.5 second animation using Procreate that is to be used as live wallpapers for the IPhone. However, I am having problems with converting it into a suitable video type that preserves the frame rate of the animation. It works fine when I download it to my phone app, however when I set it to work as a wallpaper, the animation begins to slow down/morph/act in weird choppy ways. I have tried using different frame rates as well ie 15fps, 30fps and 60fps.

I have used Procreate to create the animation and I am currently using my IPhone 15ProMax with IOS 18.5 and IPhone 16ProMax IOS 18.6.2 to test it out. I have used third party apps such as IntoLive, Live Wallpaper, VideotoLive Wallpapers, Video to Live Wallpapers Maker, Video to Live Wallpaper, TurnLive and Live Wallpaper Maker and I am getting a variation of the same result.
