I have been working with ad b2c, sucesfully configured an app and created a login flow, I have already created a login connection using MSAL library with REACTJS, and is working good. However, if I open in 2 different tabs the url login, while in the last will be sucessfuly logged, when attempt login in the first one, this will give me a bad request error.
Also, I have tried running this from user flow on azure portal and using "authorize URL", but I am getting the same error. I have been working on this for days and did not find a solution. I will be very glad to find an answer here.
If it is need more information to workaround with this situation just let me know.
@Alejandro Alvarez This is by design. As of now B2C doesn't allow multiple sign-ins within same browser session.

B2C doesn't allow multiple sign-ins within same browser session is this statement still correct almost in 2022? I'm still able to reproduce this behavior. Are any plans to improve it in the next releases?
@Andriy Bilyak · Product team is working on it. Hopefully, this will be fixed in near future.

@AmanpreetSingh-MSFT Has there been any movement on getting Azure B2C to support multiple tab login? If not is there any work arounds to not have the end users see a bad request message?
