messages on macbook sending from iCloud or gmail , not cell number
Trying to send messages from Messages app on MacBook Air. For several years I have been able to send from computer and it shows as sent from my cell number. All of a sudden, with no changes on my part, they started showing from iCloud instead. I have gone into settings and clicked on "start new conversations" from my cell number, I've signed in and out of apple ID, and I've deleted entire text chains on my macbook messages app. Still, it comes through for recipients as either my iCloud or Gmail. Help!
MacBook Air 15″, macOS 13.6
