WhatsApp is now taking a more drastic measure to stop the spread of viral messages by prohibiting you from forwarding them in bulk.
This initiative is meant to discourage forwarding viral messages restricting sharing to one chat at a time.
This feature was first introduced to WhatsApp in early 2019 and limited to 5 chats from 20.
With the new development, if you want to send the message to multiple persons and groups, you will need to select, tap forward, and choose a new chat multiple times.
Though you can still get to send the message out, it now comes with multiple attempts and limits sending viral messages that may not be true in batches.
