It's not 100% of the time but could you try on our end the following:
1) Create 2 profiles and have them opened
2) On both of them, open Gmail and login to a different account in each (for example a personal account on one profile and a professional account on the other)
3) Keep the tags open but close both versions of Orion (or reboot the computer)
4) Re-open Orion. Quite often the sessions are mixed up.
I did this yesterday, and after rebooting my computer, both profiles had my professional Github, Gmail, Youtube and Google drive accounts (instead of one of the two profiles having the personal sessions of these same websites).
The tabs will remain the correct ones, same as the bookmarks and so on. Only the sessions gets mixed up. It looks like both sessions re-open with the cookies of one of them.
Does that makes sense?
