I joined the club a few weeks back. I literally NEVER use this thing. Always leave the sunroof and fabric shade extended out. Only thing I can think of is I often crack the two passenger side windows to get airflow. I think the wind pressure pushed up enough on the fabric to break the glue joint over time. Only the passenger side sags. At least I can kind of get it rolled back up fairly neatly.
Plan is, like others, is to just tint the sunroof windows themselves more. Likely with simple static cling film.
