Child Account Management

Dear Minecraft Team, I have a Nintendo Switch with three Accounts. The primary Account is mine, I have linked my Nintendo Account and the Minecraft/Microsoft Account. Both my Kids have a Minecraft/Microsoft Accounts as well, both linked to my primary Account as family members. There are so many hoops I have to jump through when I make a purchase in Minecraft for my Kids to be able to access it. It is just frustrating. I have to go through Nintendo and Microsoft Account verification to make the purchase. Then I have to Login to my Kids MS Accounts in their Switch Profile. This ist where it gets complicated. I scan the QR code, enter the Code provided, during the login to my kids account, I have to verify by entering a Code send to their email account. So, I have to login to their google mail.. where I have to enter a verification code send to the my parental email adress. The process took so long, that there was a timeout on the initial login code. So, I did all of that again, only to be rewarded with an error message, saying the login process did not work. Madness! This is not Ford Knocks! We are trying to play a game here! Honestly, it should BE enough to enter a parental verification code ONCE in the whole process.
