Some of the blinds in our 2024 542 (the concertina type with blind at the bottom and fly screen at the top) are a living nightmare. The stick when down, and are impossible to move with a single hand. They sometimes also do not move uniformly on both sides - see this video at 1:47 to get an idea of what I mean.

Can anything be done to make them run more freely? I've never had this issue with previous caravans.
