Chat not showing up to certain players on realms

So first it was chat being cencored, all of it, now it doesn’t show up at all. Some people on reddit claim it’s because if the Xbox account settings , but so here’s my exact situation. On my realm there’s 5 people. Two on iOS, one (me) also plays win 10 but same results, another on only win 10 and another on android and another in Xbox . The ones on Xbox can chat to me I’m ios and win 10 but not the other on win 10, and also he can talk to the one on android. The one on android can chat to everyone(to clarify when I say chat I mean can see the other persons chat and talk back ) , the other on win 10 can’t talk to anyone at all, neither can the other on iOS except he can chat to the one on android . It’s confusing but basically only certain people can chat on the realm which ruins the entire realm and makes it a waste of money. Me personally I have no clue what my age was on Xbox or if it’s a child or adult. I made another account that’s an adult and added my main account to the family and made it an adult, but I still can’t chat and on the Xbox app I still have the same privelages as a child account so I have no clue what’s going on. This is evtremly annoying and if you can specifically fix our accounts like you could with the cencored thing please let me know and I’ll give you all our names. Thanks in advance and please please please help
