As of this morning I am experience #2. All my widgets are opening the same page, regardless of what they are set as shortcuts on my homescreen. It defaults to the last page I interacted with within EN. So the widget and the homescreen icons have become unusable. Any interaction with the large widget list or homescreeen shortcuts open the app on the exact same note/notebook/screen etc. Currently the only work around I've found is actually using part of the #2 bug you mentioned (double tapping back button) which returns you to the home screen which then allows you to interact with the widget/icon shortcut properly. Hopefully there will be an update of some sort to fix this.
