WhatsApp Incorrect Date of Birth Triggers Underage Restrictions

My name is Ahzsyam and I use WhatsApp regular on a Redmi 5 Plus device with the number +62 851 0161 4***. Around three weeks ago, I started to experience a problem related to the date of birth on my WhatsApp account. When I created my account, my date of birth seems to have been entered incorrectly, and now WhatsApp treats me as if I am underage and shows an error about a parental link or parental consent. Because of this, I face usage restrictions and cannot use WhatsApp normally on my Redmi 5 Plus, even though I am an adult user. My correct date of birth is 08/04/1981. I kindly request that my date of birth in my WhatsApp account be corrected to 08/04/1981 and that all age‑related or parental control restrictions on my account be removed so that I can use WhatsApp again normally on my device.
