iMesage/Text issue
When I send a individual message from my iPhone (14 Promax) to my daughter's iPhone (13) it shows up on her phone and is also sent to another phone number (she knows the person but it is not a contact in her phone or my phone). Looks like a group text but I am sending just to her #.
When my daughter replies it goes to the other number and not to me. She said this started happening last year after an update.
We used a different app to communicate but that app no longer supports SMS so that is why i am trying to get this to work.
We both have signed out of our accounts on iPhones and iPad. We both have indivual Apple ID's are not sharing our Apple Id's with the other person.
She had an iPhone SE 2020 before switching to 13 but it was happening on SE before the switch.
I switched for a brief time to an android phone, still had iPad, and I am now back on 14.
Trying to figure out if is something with my iPhone, her iPhone or carrier.
Any help would be appreciated.
iPhone 14 Pro Max, iOS 16
