The quality degradation can be so severe the videos and photos are mostly useless. They aren't literally "lost" but I've seen videos and photos that looked like a mosaic of large pixels rather than an image or video.

Perhaps the images automatically scale down during poor connection events? That isn't an acceptable behavior, modern protocols just wait, and transfer when they have a good enough connection.

Other things like tapbacks are also not technically lost, but also become useless- it responds with text saying something like "thumbs up" but not which message the response attaches to- so the context is lost, often making it impossible to understand.
