Another small thing. When receiving the notification on the windows 10 application there is a button with "Link" as text instead of the set "ut" value.
I also have experienced when logging in the first time, closing the application and restarting the application, only the first time it will not be logged in anymore. Had this in the iOS app first time using. Now in windows 10 application the same. When logging in 2nd time the issue is gone.
When this happened in the windows application it showed my e-mailadres with %40 as @-symbol and no password filled in. Also when starting the application now it first shows the login screen and then fastly changes to the logged in version. Wouldn't it be better to have a loading screen? This last thing is just a possible improvement in my oppinion, i don't think it's a bug.

Kind regards
