Unable to Join Server 1.16.1

I am unable to join friends realm when I am on playstation and they are on xbox and pc. Why is it that every other platform is able to play with everyone else except playstation? It is literally july of 2020 and I still can't play with my friends on a different console. I gave them money down for a chance to play on it and Im not able to. I have a mac as well but i can't play bedrock on mac. Literally both of the devices I can play minecraft on, I can't play with my friends after spending money. Please add the opportunity for us to play together.
