I sent a couple of texts via iMessage to a person. I was using cellular data when I sent these. The messages didn’t say they were delivered but there were blue bubbles. But after a couple hours, as soon as I was connected to wifi ,suddenly, the status changed as ‘Sent as text message’ which also means it changed to green bubbles. Does this mean I am blocked? Or some issue with the recipient’s phone?
In my experience, that happens sometimes when the iMessage protocol can’t connect for one reason or another. If that’s the cause, then future messages should show up blue. If you’re blocked, they will continue to be green.
