It is very frustrating when I set aside time to do some voluminous reading and I spend an hour of that time making sure the issue is not on my end. I don't know what Logos is doing to upgrade their app but I really hope they are spending time on the stability. When we are working on graduate studies or sermon prep we need our resources to work. I tested the app on my iPad and iPod touch and all I get it the endless swirling circle for an hour and a half now and have gotten zero reading done. This is me being frustrated right now and I had to let it out.
