WhatsApp has taken a decision during india lockdown period to limit the status of video to 15 seconds .
You can no longer send videos to WhatsApp Status if they are longer than 16 seconds: only videos having a duration of 15 seconds will be allowed.
This is happening in India and it’s probably an initiative to reduce the traffic on the server infrastructures.
NOTE: it is a temporary decision.
The full functionality will be restored in future.
