Hi! Thanks so much for replying to my question. I did some tests filling up my device disk to have only iCloud photos. In my tests, while it definitely took a bit more time for the picker to return the images, they always downloaded and loaded correctly.
Even simulating a poor internet connection by enabling the network link conditioner, I was unable to reproduce the issue our users are encountering.
Rather more alarming, the instances of these errors are increasing even though we didn’t change any code on our end. And I checked if this was due to more users using the feature, or more users updating to iOS 14, but there doesn’t seem to be any correlation. The one thing I still need to check is if the increase in occurrences are correlated to the the curve of adoption of minor iOS 14 revisions, specifically iOS 14.4, whose time of release seems to match the hike in instances. What i'm trying to pinpoint is if there's a bug on apple's end that causes this unexpected behavior.
