Ditto. Entire staff reporting same problem. When you browse and select a file, you get the dialog along the bottom asking if you want to open, save or cancel and it shows the token that Producteev is assigning to the image. But neither Open, Save, Cancel or X out completes the upload. The loading progress bar just churns indefinitely. If you click POST, it saves any notes you typed but the attachment is not included.
Wow... since 2015 and no response. Doesn't say much for customer support. Can we get some feedback on this?
