My 5th episode does not show in iTunes

[Laura Johnson]

4 of my 5 episodes have successfully shown up in iTunes on the day of posting to Feedburner. The 5th episode, which I posted to Feedburner 02.01.16, still has not shown up in iTunes. I'm pretty sure I went through the exact same process as before, including going to Feedburner's troubleshootize tab and clicking "resync now". Any ideas on what I could check?? Thanks! Laura
