According to reports, Apple iCloud for Windows interferes with video synchronization. Moreover, reports also suggest that strangers’ photos and videos appear in users’ iCloud library.
Complaints posted by users also say that videos shot with Apple iPhone 13 Pro and Apple iPhone 14 Pro are not synced properly to iCloud Windows version. Users stated that when a video is recorded and then synced to iCloud for Windows, it turns black with scan lines.
The above complaints reportedly only occur with the dedicated iCloud for Windows app. The recently launched iCloud Photos integration in Windows 11 is safe from the abrupt situation.
