Age Restriction On My Snapchat Account

I am writing to report an issue with the age restriction on my Snapchat account caused by a mistaken date of birth change. I recently changed my birth year once because I thought this information was publicly visible to everyone, and later realized I was mistaken. As a result, my account now shows me as 14 years old instead of my real age, which is 21. When I tried to correct my date of birth, Snapchat displayed a message saying I had reached my limit for changing my birthday, even though I only changed it once. Because of this, I am now stuck with the wrong age on my account, and the age restriction is not appropriate for me. I kindly request that my date of birth be manually corrected to reflect my real age and that the age-related restrictions on my account be removed. I would like Snapchat to allow me to change my birth year (or my full date of birth if necessary) so that my account accurately shows that I am 21 years old.
