WhatsApp Account Repeatedly Goes Into Review After New MTN SIM

I use WhatsApp on my iPhone 11 under the name Omobolanle D*** and for the past three days, since I bought a new MTN SIM card, my WhatsApp account has repeatedly gone into review and asks me to retrieve my account again. This happens even while I am using the phone normally and it keeps interrupting my chats and access. These constant reviews are affecting my business because I use WhatsApp to communicate with my customers and manage my work, and each time the account goes into review I lose time and sometimes important conversations. I kindly request that my WhatsApp account be checked and stabilized so that this review and retrieval process stops, and that my account remains active without repeated interruptions, as this situation is seriously impacting my business.
