The answer is No.
The limit to the maximum document upload size is set by your internet connection. PPO only allows a time frame of 10 minutes to upload documents. If the document is not uploaded within the 10 minutes time frame, because you are uploading extremely large documents, your browser might show a time-out / no response message, even if PPO is set to allow for the large file to be uploaded.
Please note that this limit cannot be increased as we have standardised the document size limit across all PPO instances. Should you need to upload documents bigger than 20MB, we recommend you zip the documents or either split the documents, before uploading them to PPO.
