I am unable to download purchased Texture packs for Minecraft PE (on iPad). The purchase itself worked, and the pack in question shows "Downloading", but there is no progress (progress bar empty) and the download never proceeds/finishes. Did each of the following several times:

• Killed/Restarted the app
• Rebooted the device
• Confirmed the internet connection is working
• Made sure there's sufficient storage on the device (there is 1.5 GB free space)
• Made sure there are no restrictions for installing apps set

I have not yet uninstalled/reinstalled the app - this step would come with possible loss of progress, and might not be helpful. Maybe you can identify the issue on your end.
