I had the same screen protector and mine broke too. Weird thing was that it broke as I was taking it out of my shirt pocket and the edge of the screen protector hit the button on the way out.

Anyway, it had a lifetime warranty, so I tried contacting the Amaxon seller. They no longer carried the same screen protector so Amaxon refunded me the cost.

I ended up going with this for a replacement:

Motorola Moto X4 Glass Screen... https://www.amazon.com/dp/B07DQVKJCW?ref=ppx_pop_mob_ap_share

It's a bit wider than the OMOTON, so it covers the edges of the screen better. That comes with a price though since the screen curves down at the edges, the protector doesn't fully adhere at the edges which may allow dust underneath. So far so good though.
