Windows 10: Default apps not available to display on Lock Screen...??

So I've been enjoying Windows 10 plenty for the most part, but I've run into my first potentially hair-tearing issue. I would like to add the Mail and Calendar apps to display more detailed information on my lock screen (simple enough, right?), however when I get to the Personalisation window to do this, I find that neither of those apps are available to add (and many others are absent as well)!!



Is anyone else experiencing this annoying problem? I'm using Windows 10 Pro, if that means anything.

Pro Camera requires password entry on lock screen

Of course, as soon as it was available on my Lumia 925, I set the Nokia Pro Camera as the default app to launch when the camera button is pressed. I noticed though, that when the phone is locked, the Pro Camera app won't launch unless I enter the lock screen
password. The default camera app did not require this, instead allowing you to take new pictures. Having to enter the password can be a spontaneity killer when the right shot presents itself.



Is this a 'feature' of Pro Camera, or is there some setting where I can change this behavior? If it is indeed a 'feature', please consider allowing access to the app without having to enter the lock screen password, just like the default camera app does.



Thank you,

 

From what I can tell by further Googling/looking around, this issue seems to effect several Windows 10 Pro users... Can any other Pro users verify this issue?
