Lightroom Mobile taking 8-9 seconds to load a photo on Samsung Galaxy Tab S7+

Hi there, I just recently purchased a Samsung Galaxy Tab S7+ however after uploading my RAW images it seems to take 8-9 seconds to load each photo imported, with the small white circle coming up and loading each one. Frustratingly, if I flick to the next photo after my photo has fully loaded and straight back, it has to take 8/9 seconds to load the same 'loaded' photo again. Every other file viewing app on my device seems to load them instantly, is there something I can do to help speed this up?

The files have been uploaded and imported directly off my device and not from the SD card.
