‘Text Message Forwarding’ is not an option in iOS 15.X Settings>Messages. So how do we share our iPhone (pj

I want to share the iMessages received on my iPhone via its phone number (email iMessages already shared) with my WIFI-only iPad Air 2. Both are running a version 15.x iOS. The option previously used for this (from wha I can tell looking in this forum) was >Settings>Messages>Text Message Forwarding. I don’t see that setting at all.

Please advise.

Thanks,

Kyle
