• VS Code Version:
  Version: 1.86.0-insider
  Commit: 9621add46007f7a1ab37d1fce9bcdcecca62aeb0

  Chromium: 118.0.5993.159
  Node.js: 18.17.1
  V8: 11.8.172.18-electron.0
  OS: Windows_NT x64 10.0.19045
• OS Version: 10 22H2

Steps to Reproduce:

1. Sign in to VS Code with GitHub for settings sync
2. Sign in to Copilot extension with a different Github account for Copilot access

(it works at this point)

3. Enable Chat extension

• it complains that my Copilot license is expired.

The account I'm using for VS Code settings sync is my old account, which had Copilot enabled for about a year;
the account I have Copilot license enabled now in is a company-bound account (this one).

Copilot itself and Copilot Labs work, but Chat doesn't and it complains on each VS Code start about that.

I'd rather not use chat at all (and currently I'm not using it, despite Copilot extension installs the chat every time, and then Chat disables it if I disable Chat, though the main Copilot extension working flawlessly without Chat).
