3.Can’t buy products:
You will not be able to buy stuff using this feature. It is strictly for sending and receiving money. WhatsApp doesn’t have a digital wallet of it’s own.
4.Can’t send money to someone with an older WhatsApp version:
Both the parties need to have the same version of the app in order to transfer money.
5.Can’t send money unless the other person has activated the feature:
