For 720p, when it happens,

TypeError: Cannot read properties of undefined (reading 'status')

Following log displays several times even if in prod mode but I consider it as minor issue as video actually playing.
But some 360p videos still doesn't play on latest commit with that log mentioned #277 so I saw log at dev mode and it looks like retrying procedure doesn't work there at all.
