Frustrating!!
Every update to the app results in difficulty getting access to your issues again. My issues available have been cutoff at November 2015 (been faithful subscriber since the 70s). And now as noted by others there is no hold/bookmark available where you left off. The whole app reloads advising an update is available. One must then go through the menu navigating to where you left off. To quote another "what imbecile thought this an improvement?"
