How to transfer a child's account from one family group to another in Apple Family Sharing?

I ran into a very annoying issue transferring my child's account from my wife's family sharing group to mine. We have a large family, 7 children, and apple only allows 6 total accounts per "family" so we had to split the kids up between us. This is an issue as well, there needs to be a way for legitimate families that have more than 4 children to provide proof of their extended family size and apple grant exceptions to the family group size. Due to the current policy of only 6, we were forced to split our family and resources. Now 3 of the Children are adults so I was attempting to remerge our family into one family group and the other forums on here were not helpful in resolving the issue I had with attempting to "transfer" my children under 13 accounts. My wife was not receiving any notification of my attempts to "invite" my child to my family group so she could release her. I finally got it to work though and these are the steps for those struggling and all the forums not helping. 1)From the target account you want to transfer to, go into the settings under your name where it says "family" (assuming you have already set up family sharing), in there click on "add member". Now, this is where you need to be careful on how you invite the child to join your family. If you have your child as a contact, at the top it will suggest to you to add them by clicking invite next to their name/icon which will send them a messenger text. Do not do this. Rather scroll down and find the option to "invite in person". Select this option and then have them log in or you log in for them and then go through the parental controls setup. 2)After you have completed the "in person" invite from the destination family group, then you go to the account of the adult who you need to transfer/release the account from, in my case my wife's account. Go into the settings on their screen and look under the primary account name at the top and under Family group and there will be a notification to "transfer" your child's account. Now, beware, on my wife's screen, it didn't just have the notification by itself below the family group, it actually was buried in with other notifications under the title "Apple Account Suggestions". She clicked on that and then saw the notification to "transfer" the child's account. She accepted it but annoyingly it appeared to not do anything, so she clicked it again, and it said "cannot transfer at this time". She tried again a few times with the same error message and then just closed out of the window. Upon closing out, she found out that the error was a false error, that it had actually transferred our daughter over to my account. For a company that claims to make technology easy for average people to understand they sure to make it frustrating to do very basic tasks and all of the error messages along the way exacerbate this. Apple Devs please add a text notification at the top of "add family member" screen that says "Transferring dependent accounts between family groups requires you to 'invite in person'" with a button invite in person at the top" before you give people the option to invite via messenger icons. This would easily fix this issue that is clearly annoying a lot of customers like me.
