Daily goals completed on web does not sync with mobile


I’ve been recently doing my daily memrise goals on the web instead of the app and just noticed that whatever I complete on web for a certain course (JLPT N2 Vocab - by BenWhately - Memrise)
is not reflected to the web app. Because of this my streak does not update on the app but it does on the website.

Quite weird because it was updating a couple of days ago. My other courses don’t exhibit the same issue.

My issue is the same as: Daily goal completed on web app shows as not completed on mobile app

They have not received a response yet.
