Incomplete sync between Mobile (Android) and Web


Lately, the mobile application and the web interface don’t properly synchronise my progress anymore.
When I play a daily course on one interface, the course appears in the top of of the screen on the other.
But the progress is not synchronized, when I reach a daily objective, the other interface doesn’t take it into account, like if I didn’t study at all.

This behaviour started a few months ago, along with the updates of the mobile app I guess.

Current setup : 2.94_21861_memrise on Android Redmi Note 4 version 6.0.1
