imessage chat split into two on my laptop but not on my iphone
Hi, recently my imessages on my laptop has split up a conversation I've been having with one person (not a group chat) into two separate conversations. I only have one contact set up for this person with both their phone number and their imessage email in it, and have changed nothing in the year-long period we have been talking.
The imessage chat split yesterday but has divided all the messages we have sent for the last month(ish) and it's honestly really annoying me.
is there a way to merge them back together?
