As others have posted, I am experiencing problems with my iPad and iPhone being able to sync with my reading plans for logos. I am operating from Vista-based PC's on Logos 4 (most recent update). What makes this problem particularly frustrating is that 4 months ago I successfully created 3 reading plans, which I have recently completed. It is unclear to me why I was able to sync before and cannot now. Those reading plans were created on my PC, and not only did they successfully show up on my iPad, but as I read on my iPad the "mark read" function updated my readings on my PC's . There are only two differences of which I am aware between now and 4 months ago; 1) I have added an iPhone, and 2) There have been updates to the Logos software.
Forum advice that I have seen has suggested two approaches to solving the problem: 1) to force the iPad app to renew its login to Logos, and 2) to delete the iPad app and reload it.
I have tried both of these approaches, without success. I do, of course, have the "Read the Bible in a Year" reading plan, which even when deleted, returns without fail... so apparently some kind of sync is happening. The "Devotionals" section and "News" sections also seem to update successfully.
I have set up a couple of prayer lists on my PC, which are not syncing to the iPad, but since I have not tried this before, I do not know if they are supposed to sync to my iPad or iPhone.
