Hi,
I found a bug with displaying pdf in OnlyOffice, for some reason there are black rectangles - this only happens in OnlyOffice on Ms Edge, Firefox, Sumatra PDF and Adobe Acrobat this file looks correctly (As a new user I can’t upload more than one image)

Here is a screenshot from OnlyOffice Viewer:

As far as I can see there is no option to upload pdf file directly.

I hope You will find the solution for that
