Salam alaykom,
I have read other posts in which users reported that their progress dipped significantly. The responses explained that grammar had just been added to the app and were told that once they established their grammar level their progress would jump back up.
I have been reviewing for several weeks now, including grammar, and my progress, which was at more than 80%, still is at 0%.
This is a known bug. There is an issue that makes it appear as if you’re at 0% progress. Please ignore that. We’re actively working on fixing it. To see your actual Quran understanding percentage, you can go to the “read” tab.
