Texts showing as from ‘infomessage’ and not from actual contact
some texts from a contact in my iPhone 11 are showing as being from ‘infomessage’ (not the contact) and I can only read them and not not reply (send fails). I have deleted and re added the contact, they have deleted and re added me as a contact but their texts still coming to me as being from infomessage. I don’t have any third party messaging apps on my phone and iMessages is off.
iPhone 11, iOS 13
