Sorry to post bug issues here - but your Report a Problem returns a 404 webpage.
Since processing the upgarde to V1.7.7, the app keeps losing my issues.
When I upgraded, I had the June 27th and July 4th issues loaded my phone. After the upgrade,they were gone, and the latest issues I could download was in March/2016.
After removing the app from my phone and Itunes, and reinstalling I could again download issues.
This morning, all issues had disappeared. I was also unable to select any past issues for download.
Again remove and reinstall the app. All issues now show as available for download. Attempted to download the July 4th, July 11th and July 18th issues. For the past hour they have been stuck at 99%.
Thankfully, I still get the print copies mail to my home.
