Teachers using GSuite services such as Google Slides, Google Doc, and others may fail to import large files via Magic Box in myViewBoard Whiteboard. 

The limitation is a result of Google API limitations that only allow "exported PDF file(s) less than 10MB in size" to be exported successfully. If the exported file is larger than 10MB, then the API will fail to generate the file.

It's important to note that file size does not necessarily equate to page numbers. For example, a file with only text will have a smaller file size when converted into PDF format.

If you need to import a large file, we recommend downloading the file as a PDF and saving it to your PC or local storage before importing it into myViewBoard Whiteboard.
