Hello Dror,
I wanted to let you know that we've tracked down the cause of the display issue you reported, and have found a fix. Posts with audio files in them should no longer be displaying badly on mobile devices, like iPads.
I apologize for the wait time for this fix! I know you have already removed audio files from your site to work around this issue, but it should be safe to re-add them if you desire.
Please let us know if you have any questions at all about the above!
