iPhone sends messages to unrelated/wrong contact
For some reason my iPhone started sending messages for Person K to Person D.
The phone numbers were never in either's contact info.
Person K has an iPhone but cannot receive iMessages sent from my iPhone. K can receive messages from my iPad.
Person D does not have an iPhone and will receive messages meant for K as an SMS.
I have removed both contacts. Signed out of iCloud. Added contacts back in. Signed back in to iCloud.
Even if I type Person K's number, it shows as a iMessage "Not Delivered" but later switches to show messages to Person D.
iMessages sent from the iPad will show correctly on the iPhone. I cannot then continue the conversation on the iPhone.
