It appears there is a bug in Lightroom for iPad. When editing an album and swiping to the next image, lightrroom will not load the preview for the next image, even though I have all of the previews stored locally on my iPad. It will literally spin the loading wheel for as long as I'll wait. The only way I can get it to load is if I exit the individual image and go into the library view, then go back into editing the same image. I made a screen recording of this.
There is also a second bug, where copying and pasting the new masking features becomes problematic. I have tried to copy and paste the Color Range and it doesn't copy over the hue and saturation adjustments individually made to that mask. At that, if there are multiple masks it sometimes displays it inside another mask for some reason.
I am using a 2021 Gen. 5 iPad Pro (512gb/8gb RAM) with latest iOS firmware and the latest available version of Lightroom for iPad on it. If there is a way I can email you the screen recording please provide me with instructions to do so.
