Menu disappears before you can tap Log In on mobile devices

On mobile devices, we're noticing when you tap the three bars top left and try to scroll down to the log in button, that the entire menu disappears before you can tap the button to log in when held vertically.

Workaround that seems to work for now: turning phone to horizontal representation or log in via desktop/laptop/tablet.

Please be specific... which devices and browsers?

I was as specific as I could be. Mobile devices are experiencing the menu disappearing when scrolling down to tap on the log in button. I own an Android. Another tester who helped me owns an iPhone. Both experienced same issue when holding vertically while turning sideways - as mentioned - seemed to help us log in for now on mobile devices. Others have texted saying they are experiencing the issue on both Android as well as iPhone. Varying browsers since Android and iPhone were used. I don't have specific browser data.

My Android, a Samsung is running this:
Chrome 90.0.4430.210
OpSys Android 8.0.0; SM-G930V Build/R16NW

Hi, Wendy, thanks for the additional info.

I was able to reproduce this issue, and I think I now have it fixed.

Can you please confirm it works correctly now and let me know?

I also need a confirmation from someone using an iPhone. I only have a Samsung Android phone, and iPhone and Android browsers work a bit differently in some cases. It looks like it is working for me on my Samsung phone.
