For the past several days, I can't make WhatsApp calls. When I try, I get a message saying:
Can't place call because this number is no longer registered on WhatsApp
So, I go to my account settings, and in "Two step Verification" it says:
For added security, enable two-step verification, which will require a PIN when registering your phone number with WhatsApp again.
So I guess I need to re-register my phone. But how? If I try "change number", it won't accept the same number, it has to be a different one. Except I don't have a different number to use. And I definitely do not want to delete my account...
What do I do?
