The same in Chrome & Brave. I surf to
mementodatabase.com and see that I'm not logged there, as i always am in the app. So where/how to log in? I must be crazy, because it seems that there is no way to do anything but scroll up & down, download, open the main (only) menu and choose among its options, none of which is Log in or Sign in. Are you kidding me?
So, what am i missing? I would send in a support request, but if I'm missing something, I'd rather not.
