There is a recurring issue when using LingQ on different platforms. When reading in browser and later switching to iOS app the reading status will not sync immediately and the user doesn't have the ability to force a sync either.
Example:
  • Reading in browser from 5th to 20th page in a lesson
  • Opening the lesson in iOS app will show reading status at 5th page
  • Using the "refresh" option will not update the reading status
  • Previously added LingQs are forgotten and still highlighted as new in the lesson
  • While reading the app will randomly update and sync the reading status on its own
This behavior means that a user has to manually find the page where they stopped reading. For me sometimes while I'm looking for the page the app will update, but other times it takes so long that by time it syncs I already found the location.
Troubleshooting steps tried:
  • Using the "refresh" button (Doesn't seem to work on iOS. When tapped, the reading status bar will flash green as if syncing the status but then returns to the local state without updating.)
  • Force quitting the app
  • Quitting & reopening the lesson
This seems to affect achievements too. Most recently I started reading in browser, then continued on iOS. The reading status was not synced and while I was catching up and re-adding the previously added new LingQs the app notified me of having reached 20.000 words which should not be possible as all words I was adding have already been added in the browser. The achievement popup was shown just as my reading status updated in the app, but I didn't receive a notification in the browser for the achievement.
Note: the issue seems to only affect desktop to iOS sync. The reading status in browser is correctly synced each time.
Recommended solution: refresh button should force request reading status from the server. In most cases it seems that LingQ stores the correct reading status but won't sync for minutes or even when this option is tapped.
