The above requires 1.66.120 or higher for 1.66.x verification 👍 @Uni-verse @hffvld as per the above, there's no specific STR/Cases that we can check to ensure that the issue has been resolved. So for the above, lets just run through a quick regression check and ensure that adding/removing items from the Playlist is working without any issues. Unless someone reproduces the issue on an older build and can verify the above.

[Uni-verse]

Verified on iPhone 12 Pro running iOS 17.3.1 using version 1.66.1 (120)

• Ensured that items in Playlist can be deleted whether saved offline or not.
• Ensured that folders can be deleted.
• Ensured that items are deleted when swiping and also in edit mode.
• Ensured items can be deleted completely after adding to playlist from various video sites for existing users.

Reopened. Please retest once we find a fix. We will add a debug menu to test performance as well

Verification for 1.66.2 was done here #39146 (comment) on iPhone.

@iccub we don't re-open issues once they have an associated PR as per the process. In this case, this already went out as well even though it was eventually reverted. It gets too hard to follow when an issue is technically in several milestones and has several different PRs associated with it. For example, in this case, we know need to remove it from the 1.66.x - Release #6 milestone even though this was part of the official release.

Created a follow up via #39286.
