None of the Samsung Services are working on my Galaxy Book 4

[kapilamayank]

So all of a sudden, all the cloud based services, or rather, any service that requires my Samsung Account to work on my Galaxy Book 4, has stopped working. This includes multi-control, quick share, Samsung Notes sync, etc. It shows on the Samsung Account app that I am signed in, but on these other apps it shows a "sign-in" option, indicating that I am not. When I click that "sign-in" option, I am not able to sign in. It loads for a while, and then shows nothing. I have tried signing out and signing back in numerous times from the Samsung Account app, but that fixes nothing. I recently used the Samsung Update App to update my drivers. I am not sure if these services stopped working after that, or they stopped before. 

Can someone help me fix this issue ?

Did you somehow upgrade the edition from Windows 11 Home to Pro? That could be the culprit.

Just checked. I am still on the Home Edition of Windows. I think something is wrong with these services themselves.

Try to remove the Samsung account (sign out) and sign back in again.

I am having the same issue... I tried signing out and signing in in Samsung account...it did not work
In any samsung app if you try to sync or sign in, it does nothing

Try using your phone or tablet to sign in via the continue on other devices feature. Do you have smartswitch or smart things on it? Will Note update and sign in. There is a website that let's you universally control all your devices from your account.

No services are working that requires Samsung account sign in

Finally!!! I think I figured it out... One of the windows Security update is the problem...most likely KB5046633...

I was facing the same problem. For me Samsung Notes not working on my Book 4 pro was a big issue. It had been more than a month and did not find solution anywhere on the internet. 

So frustrated, last night I reset my laptop and all samsung services started working perfectly.

Today I was installing windows update and after security update (KB5046633) samsung services stopped again.

I went to update history and removed it and now atleast the Samsung Notes are Syncing again. Not so sure about other services.

Now my worry is how to not update windows forever??

I can get one of Samsung Notes or the Samsung Continuity Services to work. If I sign out and sign in through the notes app, then the notes sync works, but the continuity does not. If I sign in through the Samsung Account app then the continuity service works but the notes sync does not.
