they didn't release that update for many devices yet. wait for a while and check the update in future. ( my recommendation: don't use whatsapp for the upi/ or for banking purpose. because WhatsApp is not that much sucure like other UPI apps ( like gpay,phonepay,BHIMUPI etc👍🏻)
Please perform the below mentioned steps to resolve the issue:
* Check app cache: Clear cache memory of a particular application : Setting >Apps >Now pick the app. For example 'Samsung Internet' >Storage >Clear Cache.
For further assistance, register your concern in Samsung Members Application (Open Samsung Members Application > Get help > Send Feedback > Error report/Ask questions).
