This issue with the PDF not loading occasionally happens because either:

  • the file is too large (we recommend files of less than 10MB so they reload quickly for future classes); or 

  • the internet connection is slow; or

  • the user does not wait for the upload to finish.  Large files may take a while to load with a slower speed connection (30 seconds - 90 seconds is possible)

Please be patient and if the file still doesn't load after a few minutes, please consider compressing the file first before re-uploading the file.
