I was able to get all but two of the modules I wanted installed on a new iPad, but can't load Against Calvinism or For Calvinism either by syncing with Accordance on my Mac or with Easy Install. So I deleted the modules from the User Library on my Mac and from the Accordance Library, hoping that I could reinstall (Easy Install) and then make another attempt to get them on my iPad. Neither module came up as needing to be installed.
So I moved the modules from the Mac mini via Air Drop, opened them in Accordance, and gave Sync with Mobile Device another try. No go.
