Panoramic Roof Shade -- Whats your all's go to fix?

2014 Jetta Sportwagen TDI driver here. Seeking input regarding panoramic roof shade. -- As of late late summer and through the winter, my sagging/drooping shade kept drooping and sagging more. What sort of creative remedies have you all found to fix the sag? Obviously the adhesive is worn now and just doesn't stick to the track. At times i just roll it back or say to heck with it ..
