Updated Copilot app doesn't work with Work account

If we're talking about Copilot "Business Chat" then yes, I'm seeing the same thing. Also this new version is very crippled.

I sent this complaint to Microsoft via the feedback button:

"I hate the new UX for Copilot: What used to be a standalone app at https://copilot.microsoft.com is now redirected to https://copilot.cloud.microsoft/. There is no way to change it back. IT IS NOT AN IMPROVEMENT. You removed the Notebook feature, which I use a lot. You changed the green "shield" icon, which I had been training my users to recognize as a "safe" version of Copilot (vs. the Public version, which exposes their data). You added a history bar to their chat, something I had assured the security people at my company would not be tracked. Each session is supposed to "forget" past conversations. Note, we are using the Copilot that is included with the E3 license, not the standalone M365 Copilot. This new UX is a step down. I may have clicked on "Pin Copilot" without realizing what would change. Please provide a way to change it back."

I also left this complaint:

1. Removal of the Notebook feature, which I use often.
2. The prompt box no longer accepts pasting in a screenshot. I cannot upload images, either.  I guess AI Vision has been removed from the product?  This was super useful for pasting in error dialogs and screenshots so Copilot could help me translate.  Why was it removed?  
3. The "shield" is no longer green (I had been training my users to look for a green shield so they will know they are using a "safe" version of Copilot vs the public version).
4. It appears that conversation history has been added, something that we do not want, we were told that conversations would not be stored by Microsoft. Does this mean you're training on our data, too?
5. No clear warning that this was coming, no preview of the UX, no explanation of changes anywhere I've looked.
6. There appears to be no way to change it back.
7. We are using the "BizChat" copilot that comes with E3 only, not the standalone M365 copilot.

What's kind of maddening is that I just watched the latest "Copilot Wave 2" announcement where Jared Spataro is demonstrating Copilot Pages (https://youtu.be/Gz0jPfCuvsM?si=DcqI_hlaHS2hMhSP&t=250), and the UI in his browser is the old one. Grrr!
