Bug Double sign-in required with Hub 3.0.1 and Unity 2021.2.7f1

This pattern started a couple weeks ago:

1. Wake Windows 10 PC from Sleep mode
2. Do stuff.... internet stuff. (I mention this to make the point that internet is connected, and verified working)
3. I have Hub always running (minimized to taskbar). So I double-click the taskbar icon to bring up Hub.
4. I am already signed in in Hub. I never log out.
5. I click the project I've been working on every day. (No, it's not already open).
6. Project opens. Unity says I am not logged in. That means stuff like Collaborate won't do its thing.
7. I click Sign-In
8. It opens a blank browser page and requests opening it in Hub. I click to proceed
9. Hub opens. I click that project AGAIN in the list in Hub. Says "Project already open"
10. Back in Unity, it now says I'm logged in, and it does files checks and stuff to verify if there are Collaborate updates waiting, etc.

The user flow wasn't always like this. So is this a Hub issue or Unity issue or is this the intended user flow now?
