Hi everyone,
a user just contacted me to inform me that he now has acces to the instance picker screen. Normally, this user only has access to one instance and never pass in the instance picker screen. Now, the user sees the instance he has access plus 2 sandboxes instances. I investigated a bit and saw that a bunch of users have been added to 2 sandbox. the date and time they have been added correspond to the moment I restaured backups on the 2 sandboxes. Why is this happening this way? Why all users not already in sandboxes have been added to the sandboxes? Is there someone that can explain me this behaviour. Please let me know how I can clean that and remove those instances so the user don't see the instance picker anymore.
Thanks everyone
