You need the official WhatsApp to use this account
I am currently using iPhone 15 Pro Max Unlocked and somehow WhatsApp fails to verify the integrity of the app even when it's downloaded from the Apple App Store. I have tried going to their website, which again takes me to the App Store, and no matter how many times I reset my phone, it still gives he same error when I try to register my number, or when I try to move my WhatsApp data from Android to iPhone.
iPhone 15 Pro Max, iOS 17
