iPhone x : Whatsapp videos are not playing

Hi.,

I have been using iPhone x from the past 2years. After installing iOS14, whatsapp videos are not playing in the app, but if i download to local phone, they are playing just like any other video. Could someone suggest here please.

FYI - Restart/reinstall/even iOS reinstall/ etc all possible things are tried , but, could not helped.

Thanks in advance,

Chiranjeev K
