The apps on my iPad 2 and my Samsung Note 3 have been working properly for four days now, so things are looking better. A real test will come when the April issue goes online. By the way, iOS 8.2 is now available for the iPad. I am running it now. Seems okay.
I don't want to confuse the issue, but I did experience one anomaly with the app on the iPad. After downloading the March issue, for online viewing, as soon as the %100 indicator vanished, I downloaded the offline version. When the offline version was %100 downloaded, I took the iPad offline and viewed it. Many of the pages were not fully loaded. On some pages the blurry version would show, on others the text would completely disappear.
I went back online a did another online copy download, this time waiting for all the issue's pages to show on the screen after I clicked on the 'pages"button, I did the offline download again, went offline and viewed again. This time everything was there. I speculate that the %100 indicator is not accurate. Now the funny part - I downloaded the previous two issues, January and February, and did not experience the same problem.
At any rate, everything is working properly right now.
