After some time of inactivity, (5-10 min?) all my apps return to, what I can describe as default. Example: if I make a search in my Calendar, Notes, YouTube or alike, no matter if I leave it on or switch to another app, after some time of inactivity, it all return to its default state. Very inconvenient! If I find something in my Calendar and then open Notes and begin making some notes there, using information stored under one particular date (back in time) in my Calendar, after several minutes (of not having the Calendar app opened, the Calendar app will return to today's date! On my old iPad 3 (with the first OS that it came with) the Calendar would stay opened on any date that I opened it on indefinitely, that is until I myself choose to go to today's date or any other date. The same thing happens with the Notes. Sometimes I spend long time to find something there, have it opened on the screen, and I just go away for several minutes, come back and find that the Notes returned to the last note I made! My question is very simple, how to make this stop from happening? If I open one particular note (made back in time) or one particular day (back in time) on my Calendar, on my dictionary app on one particular word, I want those apps to stay right there. How to do it?
