Does it have to be enabled via console? Don’t see any advanced mode options via the UI.

Furthermore, I am getting an error when trying to upload this pdf. It is 34 MB but I have my max attachment size set to 100 MB (in both admin settings and app.yml). What’s strange is that I have a compressed version which is 16 MB and it uploads just fine. But perhaps the larger PDF is simply too complex for now? There are lots of images, equations, etc.
