No sound on videos when sending multiple (via whattsapp)

Whattsapp/ Sound on videos:

Good morning. Is anyone else having issues with sound on videos?

When sending a batch of videos, there’s only sound on the first one.

If I send them all individually each one as sound but as soon as I send a batch it does the same thing.

I’ve tried it off two phones and it’s doing the same thing so I don’t know if it’s an iPhone update or whattsapp issue!

Anyone else having the same issue?

(same issue on 2 iPhone 15 pro max’s)
