I’ve successfully downloaded and operated it on iOS, but am running into trouble on MacOS.
2 issues arise on Mac:
The Plugin is listed in the automation file menu, but is greyed out
If it is available (a different outline, can’t identify why it would be available on one outline but not another), it returns an error once OmniFocus is launched (see image)
It’s greyed out because you have to have a top level outline item selected in OmniOutliner to run the plug-in.
I am seeing the project and the subrows added to OmniFocus, but I get that error on the Mac too, which is odd. I’ll look into why that is happening and let you know when I find and answer. If I click cancel on that dialog, I still have my item added to project on the Mac, so that might be enough of a workaround for now.
