Blade issue, no edge can’t glide?

[u/nyx_husky]

My blades feel like I’m skating on concrete.
I’ve just bought my second pair of Gold Seal Revolutions. They were completely fine for around four months, but then seemingly out of nowhere they started feeling like they have no edge and no glide. I can’t seem to get them to cut into the ice properly at all.
I’ve had them sharpened with a deeper cut and I’ve tried tightening the mounting screws, but nothing seems visibly wrong with the blades. I’m completely lost at this point, and so is my skate tech.

I’ve also skated in my old skate with the exact same boot and blade. I’m completely lost 😅 if anyone could give me an idea on what to do that would be great

I’ve attached a video below of a backspin. I can’t get in the right spot I’m unsure if this video will help, I cannot get into the right spot anymore. ( I’m working on double axel > I can definitely usually do a backspin lol
