It would be fantastic if we could add an option to disable cookie sharing between different InPrivate windows and/or tabs. I use multiple admin accounts and currently have to use InPrivate across multiple browsers today since cookies are shared within an InPrivate session. If we provided a setting to disable this behavior then I could use a single browser moving forward. This is a common problem with all browsers today and not just Edge. This feature would set Edge apart from all the other browsers on the market and very convenient for admins.
