Max Upload Size

It appears that the pro feature for uploading files to Smart Forms has a size limitation for attachments. When a user attempts to attach any number of files totaling MORE than 20MB (+/-) it will either not submit the form and provide no alert message (just spinning wheel on the “submit” button) OR display custom alert message that the form has been submitted with no entry data or email in Smart Forms. Can we increase the size limitations for uploads? Our users frequently upload multiple files and 20MB just seems to be an inadequate limitation for our use case.
