Messages app unable to send/receive SMS from iPad, MacBook Pro MacBook Air
It would appear that after recent update to my MacBooks and iPad that i'm unable to send to SMS messages. From my Macs I get "not delivered !" and address shows as "phone number is not registered with iMessage". I've logged out of iMessage on both Macs, and my iPhone.
