As always when Memrise changes something:
When you have selectable answers e.g. from 1-8, you can Access the Right field by using the mouseclick; the numbers on your Keyboard or the arrow keys (from now on up and down). But some fields will skipped or they aren`t reachable at all, Maybe the order of the internal fields is wrong……
But as always: Why do you enhance/Change Things that worked in the past??? Start with the Cursor Problem in iOS 13, now I have up to 500 words and no useable interface for reviewing, that`s annoying……
