Clarifying question: is there actual data loss here in the sense that data that only exists on the phone is lost, gone, and not synced to the server?

Maybe I am misunderstanding things, but it seems like the issue being described is that the data exists on the server, but there is not enough room to sync them to the phone so the sync errors out and the new data from the server is not actually stored on the phone (but no data is really "lost" since it is still on the server...). Sorry if I am just misunderstanding things here but "data loss" sounds really scary to me and I want to understand if that is what is really happening here or if we are just failing to sync data from the server...
