Major child online security and safety issue

there is no way in Minecraft for a parent to block sever tab access and still use a realm.

i  do not want my child accessing servers but I do want him to use my realm that I pay for. I should have the ability to use a passcode to disable sever tab access in the iOS app.

i have opened a formal complaint with Microsoft security and Microsoft legal on this issue because Mojang is not doing enough to protect  children using your app.. This is disturbing.
