The similar behavior exists with Chrome incognito mode. The workaround is to enable third party cookies in the incognito mode which Chrome has started setting to Block by default with the new releases rolling out to the Users.

There is a issue raised by Users of MSAL Angular library https://github.com/AzureAD/microsoft-authentication-library-for-js/issues/2042

This problem and the solution are documented here: https://docs.microsoft.com/en-us/azure/active-directory/develop/reference-third-party-cookies-spas

In short, react-aad needs to update to MSAL 2.0 and switch to use the authorization code flow. According to the README this was being kicked off at the end of July but there have been no updates since then.

Should be resolved by #238
