Sagging front seat material

[Fintious maximus]

5 weeks or so in to having my 5 and noticed about 3 weeks ago that the drivers fabric looks saggy after a drive and discovered that the plastic strip that holds the fabric to the seat frame had come off its fixing. I managed to redid it but the bugger keeps popping off. Anyone else got this problem. I’m thinking about taking it to the dealer to fix but am not sure that they will do anything other than what I keep doing?

Very annoying, worth taking it back to the dealer. What model is it? Excite or SE?

It’s an SE - first did it with about 100 miles on the clock and now pops off after every other drive. I’ll take it to the dealer to sort it. Passenger side never pops off
