Difference in "due" LingQs between browser and iOS

G’day Comrades,

I want to understand why there’s regularly a substantial difference in LingQ’s “due” in iOS and the browser. Per screenshots below of one lesson, there’s regularly many more LingQs due on the iOS app than there is in the browser.

Is this an error, or by design? If not on purpose, it’d be great to have the browser reflect the actual LingQs due.

Looks like the mobile app wants you to review words that are status 4 but the web app counts status 4 words as known. Unsure if the mobile app review is from a recent change but the web app has always functioned like that.

Thanks. I’ll check this with our iOS developers.
