Occasionally after typing my reply, I tap the "post" button, but nothing happens. The only way for me to post a response is to select all and copy everything I typed, click cancel and then hit reply again and paste. This then lets me post. Another intermittent issue is when expanding the reply sub comments i.e. If a comment has got 20 sub comments and I tap to expand, the app crashes back to IOS and I have to open the app again. And I have just had the app crash when I tried to open the image/video link view box in a comment. Hopefully bnet are fully aware of these issues and are working on them.
