I’ve just tripped over a new issue with Tapping Tests, where Memrise does not accept the answer even if entered exactly as it is listed in the course. Screen shot of the error and of the entry in the course below.
No, I’m not running any user scripts, I use the web application as it is served by Memrise.
It accepted the individual forms as they were entered as alternative solutions; I have removed this to avoid any confusion. The original issue is still present -ie I can enter the answer as it is in the list of the course, and it gets marked as incorrec; you should now be able to re-create this easier.
