This problem is bothering me for months, it got never fixed. If the audio in a lesson ends and you try to start it over or from a certain point, it will go and immediately stop, will do the same things for some minutes, even if you open another lesson or refresh the page. If you go back just before the audio end it won’t be a problem, but I just can’t stay for minutes looking at my phone waiting for the audio to get close and then go back. This problem totally ruins immersion and the studying plan, because it take a lot of minutes in witch you won’t be able to listen to anything. Please fix. Happens in any language and there is no solution by now other then waiting at least 15 minutes.
Sorry to hear that. Is that on the app version? If so, iOS or Android app?
