Unable to change/edit privacy settings

First of all, you need to check your personal information to ensure your birthdate is correct and reflects that you are over 18.

To do this, you need to sign in with your Microsoft account.

Once signed in, attempt to change your privacy settings from there.

Besides, Even though you mentioned being the only member in the family group, it's good to double-check.

Go to family.microsoft and ensure that your account is not listed as a child account in any family group.

Hi Golololololol, my name is Jose, an independent advisor, and I am delighted to assist you.

Unfortunately, the answer to your question may vary depending on the specific platform you are using to access Minecraft and its associated security settings. Here are some general suggestions that could help you solve the problem:

Check Account Settings:

Make sure you have logged in with the correct account.
Review privacy settings directly on the account, if possible, rather than through Minecraft.

Verify Age on the Account:

Confirm that the birthdate on your account is accurate and reflects your current age.

Contact Technical Support:

If, after reviewing the settings, you are unable to change the privacy settings, contact the technical support of the platform or service you are using for specific assistance.

Switch to an Adult Account:

In some cases, it may be necessary for the account to be registered as an adult account from the general platform settings rather than specific Minecraft settings.

Review Family Security Settings:

Make sure to review family security settings on the platform and ensure there are no additional restrictions.

Consider Creating a New Account:

If all other options fail, you might consider creating a new account with the appropriate age from the beginning.
Remember that specific solutions may vary depending on the platform or service you are using, so it is advisable to consult the support documentation or contact customer service for personalized assistance.

If you have any further questions or need additional assistance, please do not hesitate to contact us. We are here to help.

Best regards,
Jose.

Try to change your privacy settings via your Xbox & Xbox.com, if neither work. Try MeanMachines suggested answer and see if that helps.

Im not sure that it would help, but you could always try clearing the cache, just incase, or uninstalling just the account profile and redownloading it.

Hi there, Grid.

Is there a sentence or is it simply just saying "Error"?

You could try a hard reset - hold down the console's power button for 8-10 seconds until the console powers off completely and you can see the orange light on the power supply unit. Leave the console off for a couple of minutes and then power it back on.
Attempt to try and change your privacy settings again.
