Dear @WhatsApp
You have a huge number of users in India (close to 500 million).
You should update privacy settings & give option that 'only saved contacts can call'.
The cases of sextortions and scams from international numbers (ISD codes) on WhatsApp are on the rise in India.
If your invoices reflect in GSTR 2A but not in GSTR 2B and you want to file your GSTR 3B then you can file it on self assessment basis using GSTR 2A
GSTR 2B will be available at the earliest
