In Mac OS Tahoe, Messages, I only see "Messages, Spam & Recently Deleted"
In messages on my phone I have several sections of "folders" including Transactions & Promotions. Those weren't showing on my Mac. But some messages were being filtered into there. I had no way to see them.
It turned out that I needed to turn on "Screen unknown senders" on the Mac to see those folders. Having it on, on the phone, moved messages there, but I couldn't see them. It also needs to be turned on, on the Mac.
Just wanted to post this because I couldn't find the answer on the internet and maybe someone else will find this post when they have the issue.
