Facetime strangeness
So on my iPhone SE 15.3.1, I call up a contact. I am offered the option of "Video". I press that, and the text "Facetime" is displayed, with a choice of phone or e-mail. I go with phone. From then on EVERY OTHER CONTACT I OPEN offers me "Facetime", instead of "Video", and doesn't offer me any options of phone versus e-mail. Just goes with phone.
Why did the options change? Why am I not offered to do Facetime to an e-mail address anymore?
