Ask HN: Can You Log into HN with Firefox on Android?

This morning, I've been unable to log into HN from my Android on Firefox. Anyone else experiencing this? I click 'login' at the top of the page, paste in my username and password, click the login button, the page re-loads to the front page of HN and I continue to be logged out. This might be the first time attempting to log in since I installed the latest Android update. Not sure if that is related.

Firefox 68.2.1, Pixel 2, Android 10
