Messages on Big Sur no longer getting/syncing SMS messages

As of today, new SMS messages no longer appear on my MBP running Big Sur. I downloaded and installed Big Sur last week and it had no issues immediately after but today I've been running into a lot of issues even though all my settings are set up correctly. SMS messages do not get forwarded from my iPhone to my MBP and so I missed out on some one-time activation codes until I noticed. SMS messages I send from my iPhone do not appear on MBP. If I send SMS from my MBP, it tells me it was not delivered but then I check my iPhone and it was. iMessages I have no issue with so far so I was wondering if this was affecting anyone else?

MacBook Pro 13″, macOS 11.0

Two part solution for me:

1) My Calls on Other Devices (Settings - Phone) was off as well. I have an old setup with separate Apple & iCloud Ids. I had to make sure FaceTime and Messages on both phone and laptop were all logged to the same account to be allowed to turn this setting back on.

After that, I still wasn't getting or able to send SMS on my laptop (M1-Big Sur).

Then, I found this on an Apple page

"On your iPhone, go to Settings > Messages > Text Message Forwarding.*"

This let me choose the devices that received SMS texts. Turning it on for my laptop immediately resolved both sending and receiving issues.

I have an iPhone 7 running the latest software for it (14.2). My "allow calls on other devices" setting had been changed to off. I tried turning it on for all my devices, but when I went back to the main screen, it was off again! Does this have something to do with my having an old phone? Or is there another solution? I just got a new M1 MacBook Air, which is where I noticed the problem happening (missed notification codes sent to my phone, etc). Other devices include an old iPad 2. If there is one old device in the message network, does that throw everything off?

Yes, text message forwarding is still enabled.

Have you tried disabling text messaging forwarding, restarting the phone, and then enabling it again?

Yes, I have the same issue on my iMac, also running Big Sur.

Exact same issue here. No doubt a bug as it seems like it applies to many of us.
