Adobe's Recent Lightroom iOS App Update Deleted User Photos and Lost Data is Unrecoverable
Adobe's recent 5.4 update for the Lightroom for iOS app had a major bug in it that deleted user photos and presets, eradicating all content that had not been synced to the Adobe cloud service.
Affected users lost photos, presets, edits, watermarks, and more. One user on Reddit said that he lost two years of edits, and there are dozens of similar complaints from people who lost important data. The problem affected users who were using local storage without having uploaded that content to Adobe's cloud storage service.
Many of those affected were using Adobe's free service, which has limited cloud storage, but some paid users were also impacted and lost thousands of photos.
Adobe on Wednesday released a 5.4.1 update to prevent the bug from affecting additional users, and confirmed at that time that none of the data that was lost is in any way recoverable. From Adobe:
A new version of Lightroom mobile (5.4.1) for iOS and iPadOS has now been released that prevents this issue from affecting additional customers.
Installing version 5.4.1 will not restore missing photos or presets for customers affected by the problem introduced in 5.4.0.
We know that some customers have photos and presets that are not recoverable. We sincerely apologize to any customers who have been affected by this issue.
Adobe has recommended that affected users try to restore an iCloud backup that might have the lost content, but there's no solution on Adobe's end to address the loss and no fix if there's no iCloud backup.
