I just recently converted a PCL project to Netstandard. I'm slowly trying to work through issues. Since our popup code no longer works, a derivative of XLabs, I'm trying to use this new plugin.
Download the demo project and running it works fine. When I use the exact same code in our project all I get is a dimming of the screen. I can tap on the edge of the screen and it goes away. So its doing something. OnAppearing is being hit so it's rendering. I'm using the same xaml and code behind from the demo, specifically the LoginPopupPage.xaml
The project is using master/detail if that matters. Rg is being initialized in OnCreate in MainActivity.cs. I have it referenced in the droid and netstandard project.
