Troubleshooting login issue with older studios in Firefox and providing workarounds.

Hello! I am logged into www.sanity.io/manage but when I try to go to my studio URL, I can't log in and can't do a password restore. What can I do?

Since I see you answering questions today: any advice? We're locked out of studio (both I and the other team member). Is there anything we can do?

Hey Felix! I might be able to help you out, too. Can you please DM me your Project ID, and email address?

Thanks, will do!

Okay, we were able to troubleshoot this issue, and solve the problem! It’s in the best interest of the community to share solutions publicly, but also obvious ensure that PII remains private.
In this case, the cause of the issue is related to the way that older (v2) studios authenticate users with cookies, and it was specific to Firefox. There are two workarounds:

• Try to login using a Chromium browser like Chrome or Arc
• Disable Enhanced Tracking Protection in Firefox
This particular issue should only affect v2 studios.
