Login in Android not working because of unsupported browser

Here: Android 13, Moto 54.Standard login, 2-factor code.All good with the credentials. . Ends up in a browser session. It then pops an “unsupported browser” message, asks to click on the […] menu upper right corner and “Open in app”. There is no such option. Neither in vanilla Chrome or in Firefox.Anyone else has the same issue and/or a workaround?Tried reinstall/cache clear, the works. It looks like they delegate to the Android’s browser for login purposes and then loose their way back into the app. Somehow.
