I did a factory reset on my Oneplus 6, put in my wife's simm and set it up. Everything works fine except she can't receive texts from our son who is on the same account. She can send him texts. I've checked for blocking and deleted the contact. She can receive group texts from him. Tried clearing the storage an cache under apps. No clue what else to try.

I changed some setting in the app, but I can't remember what it was. It suddenly started working.
