Hello,
My name is Vladimir and I work as a developer of a video-based language learning app - https://itunes.apple.com/us/app/fluentu-learn-language-videos!/id917892175?ls=1&mt=8
Recently, our team has faced the issue that we have been struggling to fix for a while.
Steps to reproduce:
1. Open the app and log in with any account
2. Use slide (not tap) gesture to open main menu: http://screencast.com/t/QtaXaYoAW, http://screencast.com/t/DADhinX6xwzs
3. Open "Browse" page or any other page with the video player
4. Start playing a video.
Actual result: All videos in this case play with stuck picture (sound is normal though), i.e. video is frozen but the sound is playing - http://screencast.com/t/l5Q43SqrHj
It seems that this issue emerged after we switched from UIWebView (because we were experiencing crashes under iOS9) to WKWebView library. Please note that we use YouTube player in the web view.
Could you please advise us how this issue can be fixed?
Thanks,
Vladimir
