Will deleting the referenced materials affect the store's users?

There are two scenarios:

1. Delete images/e-books: After deletion, the positions where the images/e-books were used can still be displayed normally without any impact.
2. Delete audio/video: After deleting the audio, when users play the audio, they will receive a voice prompt saying 'This audio has been deleted by the merchant'; after deleting the video, when users play the video, they willsee the message 'This video has been deleted by the merchant'.It is recommended to delete the materials only after confirming that they are useless.
