WhatsApp users will have “limited account functionality” if they don’t accept the new terms. These WhatsApp users will not be able to access their chat list but they will be able to answer voice and video calls. WhatsApp will also allow these users to call back a missed voice or video call. Notifications will also continue to arrive and users will be able to read the messages and respond to them as well.
However, this will proceed just for a few weeks as WhatsApp will ultimately bar users from receiving incoming calls or notifications essentially cutting off services. This means that users will have to accept the new policy or end up losing their WhatsApp account.
