Video abruptly fails in new update, b30

[EmbersFlying]

For some reason, on every video I watch, the video stops playing less than 2 minutes in. This happens every single time, regardless of whether I'm using iOS or Android app data, and I'm not sure what to do.

I opened the debug log to see what was happening, and found that a bunch of these errors started appearing whenever this happened:

[ffmpeg] root atom offset (hex #): partial file

I've never seen this happen before... is there any way to fix it?
