With a clearer head, I was able to figure out the passcard auto-submit function. They were filling but not submitting about half the time, and I think I figured out why. Robo waits until everything is loaded before it will perform the fill and submit, which can slow things down, and I had to load them one at a time.
Sometimes loading multiple pages, and filling them yourself, moves it along faster. This has been my experience.
I was having that problem too. After trying various different methods, I am opening the passcard editor, clicking on one passcard, then going down about 20 and hitting shift + enter, and then doing "go to". I used to be clicking on each one until I figured out I could just highlight a whole group and open them. (i think that is what you are doing as well?)
They don't autofill and submit that way, just opens all the pages, and then I just go along the tabs in Firefox and click fill and submit for each one. And then go back along the line and close each one.
I was also using IE before doing this method and it is much easier to use it in Firefox with the tabs right next to the fill and submit button (took a day or two to get used to it).
The "problem children" or "first time added" go in their own folder (and then join the easy "grown up" folder, when I make sure they are submitting correctly ... and if in a hurry will just do close all tabs in the "grown up", hoping that it is behaving correctly, but do make sure and check it every couple-three days, because sometimes a random grown-up passcard randomly acts up!).
Those that "fill and submit" doesn't work with just one step, I put in separate folders. (flash, multiple steps <just put in two or whatever passcards for those>, codes, etc.)
Has saved me a bunch of time over the way I was doing it before and is also faster for me than clicking straight from the passcards menu. But everyone probably gets used to their own method. Whatever works
