An InvalidCastException is thrown when importing documents containing outlines with an invalid destination set:
The exception:
System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfReal' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName'.'
When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened. An InvalidOperationException is thrown with the message "Password is not correct." when importing with PdfProcessing; Adobe Acrobat also doesn't recognize the password.
Workaround: Exporting with AES256 encryption does not have this problem:
provider.ExportSettings = new PdfExportSettings
{
IsEncrypted = true,
EncryptionType = EncryptionType.AES256
};
When importing a document with a missing state separator (e.g. linefeed) in the object stream (ObjStm) an exception is thrown: System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfDictionary' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'.'
А possible workaround could be handling the exceptions: Handling Exceptions.
Wrong calculations of new lines and white spaces between characters due to a wrong calculated character`s BoundingRect.
This results in missing whitespaces and/or characters split between lines.
Currently, a known limitation is:
RadPdfProcessing currently supports only signing of a single signature field. Signing more than one signature field will result in invalidation of all signatures except the last one.
Please support signing multiple signature fields. We are heading into 2022 and it's more essential than ever to be able to sign multiple signature fields.

Allow table spiting to be done on whole rows instead of splitting the content of the rows.
Attached is a small project that shows a possible workaround.
From the PDF Specification: "An ink annotation represents a freehand “scribble” composed of one or more disjoint paths. When opened, it displays a pop-up window containing the text of the associated note."
When writing a RadFixedPage containing widgets using the PdfPageStreamWriter.WriteContent() method an exception is thrown.
The exception: System.ArgumentNullException: 'Value cannot be null. Parameter name: context'
Workaround: Set explicitly the the ImageCompression filter:
PdfFormatProvider provider = new PdfFormatProvider();
provider.ExportSettings.ImageCompression = new ImageFilterTypes[] { ImageFilterTypes.FlateDecode };
