Whenever I open an app that I used 2-3 minutes ago (sometimes even after 20 seconds), it starts opening the app with full loading like it was not used for days, especially with Facebook, Messenger, Viber etc. Most annoying one is Edge, definitely, which loads web page I was browsing every time I minimize the app and enter it again. I'm using Lumia 640XL DS (Insider Release preview) with only 1GB of RAM, so it could be that. But shouldn't it remember where I was when I "minimized" the app and just continue working when I enter it again?
