The place where it warns you about apps needing updating used to awe me - it was like having unanswered letters and felt like a standing reproof, I couldn't bear to see more than two or three there. Now I am more relaxed and thirty there dont bug me. But then I'll have a blitz on them and update twenty. I update them if they sound like something that could concern me, like 'bug fix' or 'stability improvement' etc. but some of them only say something optimised for I-watch or I-phone - and I don't have either. So am I wasting memory if I update these? Is there any point? Can I get rid of these warnings? Does it matter one way or the other? Related point - also outstanding, being ignored and not updated I have ios8.3 in 'Settings'. The reason is last (or so) time I updated iOS there was some problem I don't remember but I then saw discussions on the net saying don't do it, it has bugs not yet ironed out. So i wondered, is it now safe to update 8.3?
