I think I’ve actually fixed this issue. For reference, it ended up being that the Rows in SPB that the content was housed in had a custom Row ID and Row Name. Not sure why, but that messed with mobile Safari & Chrome on iOS. I went through and deleted the Row ID and Row Name in each of those pages, and have not encountered this issue since. Odd bug.
The latest issue I am having (see new ticket at: http://www.swiftideas.com/forums/topic/icon-box-assets-not-appearing-on-mobile/ ) is the icon box grid doesn’t work on mobile (or it does load, but 2 mins after the page is requested). I double-checked, and the Row ID issue is not there for that one. There seems to be a similar issue on Dante ( http://www.swiftideas.com/forums/topic/icon-boxes-missing-in-mobile/ ) but I’ve cleared my cache, used incognito, everything on multiple iPhones & iPads, with the same issue.
I’ll mark this ticket closed.
