I recently sold my MBP and got an iPad Pro. So now I have my huge list of messages on the iPhone but cannot seem to get that to populate neither the iPad or iMac message app. Have checked every setting and all identical as can be. Signed out and in to iCloud on iMac and iPad yet still nothing. Unsure what more to do to force the Messages app on iMac and iPad to load up all the conversations from the phone. Anybody have any advice?
