If you download the pdf document from the internet, save it to the device and try to show it inside PdfViewer, it will not be loaded on Xiaomi phones with MIUI 12.1. and above.

Users report similar issues with downloaded files on MIUI devices, here are a few discussions on the matter:

https://www.reddit.com/r/Xiaomi/comments/mx05ur/file_downloading_issues_on_my_xiaomi/

It seems that's the same reason for the PdfViewer not showing downloaded pdf files as it properly shows pdf documents added as embedded resource to the solution.

iOS SDK 14.1, ARM64. Happens regardless of Linker Behavior setting.

The page itself has nothing in its code-behind other than the default constructor calling InitializeComponent(). In the XAML, the RadPdfViewer control is in a two-row, one-column grid, where it is in the second row:

<Grid VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" ColumnSpacing="0" RowSpacing="0">
    <Grid.RowDefinitions>
        <RowDefinition Height="60" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>

    <Frame Grid.Row="0"><!-- ... --></Frame>

    <pdf:RadPdfViewer Grid.Row="1" HorizontalOptions="Fill" VerticalOptions="FillAndExpand" Source="{Binding Source}" />
</Grid>
The view model has a DocumentSource property Source and implements INotifyPropertyChanged. However the exception occurs before the BindingContext of the page is set to the view model.

When RadPdfViewer is used in a master-detail page, I should maintain the previous page index when I traverse between pages.

Please add a search option to PDF Viewer.

It will be great If you can also add a thumbnail preview option to view all pages in the PDF and a page slider to help navigate user to any page in seconds.
