If I use iMessages on MacOS running 10.13.5 and click the 'X' or swipe left to delete a conversation, it does not delete across all my devices only on the Mac. There's no message, no warning, etc. and it's deleted locally. Instead, if I right-click and select 'Delete Conversation', it notifies me that it will delete the message across all my devices. That doesn't seem quite right and a bit counter-intuitive. Is anybody else experiencing the same behavior? Is this expected behavior? If I delete a message using iOS, it will delete across all my devices including my Mac. Thoughts???
