iMessage 💬 empty bubbles
When using iMessage on my iPhone sending pictures and attachments works fine, received and logged on my phone and MacBook by myself and others. However when sending pics and attachments from my MacBook they send as empty bubbles. No issue with sending, just nothing shows on my phone or others. This has been this way for years, and multiple software updates. It used to be fine on my iMac, but when I upgraded to the air I think I did something wrong in the settings and cannot figure out how to correct. I know others with the same issue and Apple does not seem to have any issues when you reach out to them.
Please help!
MacBook Air 11″, macOS 10.14
