We installed Survey123 on our Enterprise 11.3 deployment. Created a survey for staff which includes a couple questions asking for pictures. I have the file size in the question at the maximum of 20 MB but it won't allow me to actually upload anything bigger than 1 MB or so each (haven't tested the actual limit, but that's what I had to test with). Two 2.5 MB pics won't even go.
So, is this a bug, or is there another configuration setting that we can use to allow larger attachments to match what the form says it can handle?
