How to switch between Box instances

I access two different Box instances for two different companies, Company A and Company B.

My Box account username is my Company A email address. Company A uses Box Discovery. I can login to the Company A box instance normally. (After I go past the “Part of Company A?” → click “Continue” page, box Discovery will pull up Company A’s SSO login and I am able to access the Company A box.)

when I try to access the Company B Box I have a problem. When I get to the “Part of Company B?” -> click “Not Part of Company B”, The next page that loads prompts me to enter my box account email address. I enter my “ [removed by moderator] ” username and click continue which I expect will take me to the “enter password” page. Instead, when I click continue, Box Discovery redirects me to the Company A SSO login. I am not asked to remain on the Company B instance, and am never able to access the Company B Box as I am always redirected to the “Company A” Box by Box discovery.

This Box discovery redirect has only been an issue in the last month.

I have a coworker who does the same steps when logging into the “Company B” Box, but after they enter their username, they are presented with a redirect page that asks if they want to be redirected to the “Company A” box, or stay on the “Company B” Box. No matter what I try, I cannot get the redirect option page to display and am always forced to the Company A SSO login page, and therefore can never access the Company B box.
