The PopSocket adhesive is designed to stick to most materials, but has difficulty with some silicone and waterproof cases and anything with too much texture.
The awesome gel on the back of your PopSocket is designed to be reactivated. Simply rinse it with water, air dry for 10 minutes and then firmly reattach to your phone case (don't leave it unattached for more than 30minutes because the gel will die). Resist the urge to Pop it for at least 1 hour and this will take care of the problem!
