Since getting the iPhone 7 I can no longer add a group name in text messages. Suggests?

you can only do it if everyone in the group is using an Apple device - blue text imessage

you can't do it if someone is using an non Apple device - green text MMS

Send a group message on your iPhone, iPad, or iPod touch - Apple Support
