MSAL Logs

I was not able to get trace logs from mobile Edge, but you can try the issue by yourself:

Here is console log (about:inspect) from mobile Edge:

Hey @jkytomak the error indicates that the popup was closed by the user or it could be blocked by the browser. When I try to repro the issue, I see a new tab open to enter my credentials. Can you confirm if this tab is opening for you? If not, you need to check if it is being blocked by the browser.

[jkytomak]

@lalimasharda yes, popup opens normally, but after I select / login with some account from popup, it does not close and those errors come to console / api.

Please see here - popup is not recommended in mobile browsers as support is very limited. What Edge is doing here is "closing" the popup and then re-opening the url in a new tab which causes the original calling page to lose the reference to the frame doing the sign-in. We recommend using redirects for interaction in mobile browsers
