Xodo PDF Reader & Scanner funktioniert nicht

Text and signature fields; list, check, and combo boxes; radio buttons available. - Create a custom toolbar for quick access to your favorite features - The favorites toolbar allows you to build your own toolbar using any number of our existing tools so that it works exactly the way you need it to. - Use Smart pen to streamline the note-taking experience - Making note-taking workflows a breeze.  This is not simply adding rectangles over content - the underlying content is completely removed from the PDF. - Compress PDFs - Export a file-size reduced copy of the PDF that will use less disk space. - Merge multiple PDFs into one - You can append a PDF with another PDF using the "add pages" functionality. - Create PDF forms - The form builder allows you to create fillable PDF forms for others (or yourself! ) to fill out.  The Smart pen tool will automatically create a highlight annotation when you draw over text, and an ink annotation when you draw anywhere else. - Annotate in Reader mode - When viewing a PDF in reader mode, you can highlight, underline and strikeout text. - Nested layer controls - PDFs that include multi-level layers can have their visibility toggled individually.  Use the lightweight and snappy Xodo app to save time and boost productivity when dealing with PDF, iWork, and MS Office documents on your iPhone or iPad. - Convert PDF to Word, Excel, PowerPoint, and HTML - Xodo's conversion is focused not only on matching the PDF's look, but also the editability of the output.  You will not find another converter that performs consistently as well as Xodo PDF Converter & Editor. - Redact sensitive information - The redaction toolbar allows you to permanently remove content from your PDF.  Both free and premium app versions support different view modes (single page, facing, reader mode, and more) as well as light, dark, and sepia color modes.  You can also search for specific text inside long PDF documents and Xodo will automatically re-open files to the last-visited page so you can pick work up where you left off.  With Xodo PDF Reader & Scanner you have full access to all of your device's files and cloud documents.  Whether you want to highlight class notes, alter a recipe, adapt blueprints, revise and sign contracts, fill in forms, or just read a good book, Xodo simplifies your life.
