Following up on: https://feedbackassistant.apple.com/feedback/22501602 We have a downloaded .movpkg (via AVAggregateAssetDownloadTask) where we need to update #EXT-X-DATERANGE tag URLs in the manifest Apple Developer Technical Support (FB15965814) confirmed "it is perfectly fine to update the m3u8 playlist inside the movpkg if that works well for you." Can you confirm this is safe to rely on long-term and won't break in future OS updates? Is there anything we should watch out for (e.g., movpkg integrity checks, asset download storage manager interactions)?
