We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Files that are less than 10 MB can be downloaded 100 times, while those that are greater than 10 MB can be downloaded 10 times.
Currently, this is the limit we have, you could always download the file in your local storage to easily view it, you can also take advantage of the file sharing storage services like Dropbox and Google Drive where you can easily upload the PDF submission and the file uploads automatically when a new submission has been made.
I hope that helps.
