Did you remove the shine first?
D solve should be fine.

I must admit I still struggle with Gelish removal - I agree D solve works just as well as harmony's remover.
I've tried removing the shine, heat etc but it does not compare with Shellac's removal
If the clients nails are dry to start with then it's even harder to get off.
Using cuticle oil makes a huge difference to removal but it's still hard.
I don't remove the shine before Gelish application either as it makes no difference to how well it lasts. X
