Awesome job! I noticed two issues on your landing page which I didn't see mentioned yet.

The first link in the nav bar points to the frontpage but it's not shown as active and that isn't apparent from the link text either, so it seems like a broken link.

The "Open app" & "Get started" links break the browsers back button. These are the first links I'd click, and at this point I have no idea what I'm even signing in to so I'd want to go back and explore a bit before... but since the back button doesn't work, I'd just close the tab and forget about it :)

I would also throw a lock icon on the button to signal the fact that login is required.
