Lightroom slow to load smart previews on ipad pro 2018 - why?

[#1]

I've built smart previews on my laptop and then synced them to my ipad pro, but it takes a second or two to load each poto when editing. I have fast internet and can't think of another reason why. Any help would be hugele appreciated.

It has to download from the Cloud. The second time you open a previously opens image I would have though it would be better as it is cached locally.

One option would be to store the Album locally until you have completed your work on it.
