I just had someone contact me this morning about this very issue.

He is on Android and can't download anything through the app. He tried reinstalling the program to no avail.

I am on Android too, but I can download filled without issue.

OK, I have looked at all of my devices and they are finally all showing the most current sermons, which is great. 

I didn't do anything to the Android or Apple phones.  I'm not sure why they finally started working.

I did update an older iPad to the most current OS and that seemed to help AC Central.  

Thanks.  I can happily use this app again!

Sorry, I missed the reply a couple months ago.  Thanks for re-posting.

The issue appears to be resolved on my Android device.  It is showing the latest sermons for the first ever, I think.

I'll check the iOS devices this evening.
