Recently my Difficult Words on Mac (iOS and Desktop) are not adding words answered wrong. It’s always worked fine before but suddenly nothing is being collected despite purposefully getting words wrong multiple times to see if they’ll be added. Problem started around April 9th for me.
As an update I restarted the course and Difficult Words are now catching. A bummer to loose 400 planted plants but love the site and what it does. Hopefully this bug can be squashed though if it affects any other courses.
The problem first occurred in a custom course I made right around when the redesign launched.
