Hi! Is there supposed to be some sort of dialog box when I hit "Upload"? It seems like nothing happens after I try to click the upload button, no pop-up or error msg. I tried to save the ruleset first but it's still the same.
After you upload, hit the download button and verify if the file has been uploaded. Also check the tracer file if there are any errors. Ideally after clicking the upload button and selecting the desired file you have to save the rule. With this the file should've been uploaded.
