Common

[ABR-139316] Validation of a backup that was created in the v11 format and includes Microsoft Windows Storage Space partition fails with the error "No current partition".
[AAP-3602] The installer repair fails if Active Protection is enabled and the agent was updated via live update.

[ABR-260477] After changing the backup format from v11 to v12 in the protection plan settings, backup replication to a cloud storage fails with the error "The archive is invalid or its type is unsupported."

[ABR-254782] Users cannot change their credentials for the network shares selected as source for files or folders backup.
[ABR-216182] Recovery of disks/volumes fails when the target location for recovery is a removable drive – for example, an external USB drive.
