You aren't able to create an account based on the information that you provided. Child's Account

It's obvious from searching online that this issue has been happening for years and has never been resolved. They've released the newest version of the device, but did nothing about fixing the issues. It's not ok that the only response on here is the same generic copy and paste message, literally the whole point of a forum is for someone from Meta proving a proper solution so that all can see, opposed to asking them to send a PM that never gets a response anyway and its because theyre in mo way bothered about addressing it, so there is no solution.

Considering the hefty price for the device and that this is a multi billionaire company, the customer support is just absolute dog **bleep**e and they do not seem to give any disregards in fixing any of these problems.

I'm disgusted and quite pissed off! I'll be returning this to the store and getting a refund and will await for a rival company to release their alternative to this. 

Get it together Meta, it's a disgrace!

Hey everyone, I've just heard back from our internal team. It looks like in most cases, they've found that this type of issue is brought up when an invalid date of birth has been input. (I would assume one that is under 10 or over 12)

If you've already attempted a few times now, I would recommend waiting a few days before trying again with the right information. This way the app can get a fresh read of your information like new. Let me know if anything changes or not and I'll be happy to pass it along! 

SOLUTION FOUND!

I WAS FINALLY ABLE TO CREATE A CHILD ACCOUNT BUT ONLY AFTER GOING INCOGNITO MODE IN CHROME. I could not create a child's account on the app or on Chrome in the normal mode. Give it a try guys. Hopefully it'll work for you too! By the way, Meta Support was absolutely useless in this matter. Happy New Year!

I just tried through incognito on the Brave browser and it worked. Thanks for the tip!

THERE IS A SOLUTION, Y'ALL!!!!   

I do not know where to post this so people can find it.  I have spent HOURS on chats and trying to create a child account.  I was doing so on my phone.   I logged in from my computer and created the child account with no problem.  I am pretty upset with the customer service.  it was so frustrating.

Hi, did you find a solution to this problem?   My son has been playing under my name since December because I keep getting this same error message.  

 Its pretty crazy that this issue is this old and still hasnt been resolved. I have 3 kids, all within the age parameters. 10, 11, &12 and it only let me add ONE supervised account and won't let me add another. Best part is my wife tried to make her own account after I did (on our PC because the app is a dumpster fire) and it gives her the same error as well.. how absurd that my kids cant use their $500 christmas present just because meta cant figure their website **bleep** out

Mera umra 25 saal se adhik hai kripya meta ai ka asses diya jay

I was able to create one child account. I’ve tried to create a second child account, kid is 12, and I get the something went wrong message after I enter the birthdate. This has been the most annoying experience.
