Ring Flood Light cover detatched

I went out yesterday and saw the cover in front of the lens of my Ring flood light blowing in the wind. It seems the glue has lost its adhesive properties and it just popped right off. I had to tape it back on temporarily while I seek support. Can I get a new plastic lens cover? Should I just glide this one back on? You can see a crackley ring around the outside of the lens, that was the Glue from the factory.
