My film scans are in jpg format.
I import them into lightroom for editing and syncing with the creative cloud.
On the lightroom iOS app the jpg previews are really pixelated, but on the mac app they are full resolution and look fine.
On the iOS app the raw files from my digital show up fine with no pixelation.
I have the 'download full resolution' button checked so no idea why this would be happening.
try selecting all photos than go to library/preview build 1:1 previews and see if this solves problem?
is this in the lightroom iOS or mac app?
