Mac doesn't send or receive Messages while iPhone does
Messages on my iPhone works as it should, but I'm only able to view past conversations on my Mac. I'm also unable to send or receive messages on my Mac. Wondering if anyone else is having this issue or has a solution? I read that back in March there was a software update that screwed some things up, but I'm assuming that's been fixed already?
I appreciate any advice.
(Edit to add: I'm running macOS Big Sur 11.5.1 which appears to be the latest update)
(Edit 2: Messages also appears to not be synced, because when I delete messages on my Mac, they still show up on my iPhone. I did go into Messages > Preferences to check, and after manually syncing it, it still appears to not be.)
