I was lucky enough to receive 3 items from Yootech, and the third one is the Galaxy S8+ Screen Protector [2-Pack][Galaxy S8 plus,Not Glass], Yootech Galaxy S8+ Wet Applied Screen Protector BUBBLE-FREE for Samsung Galaxy S8 Plus.
I have the Yootech Galaxy S8 Screen Protector [2-Pack][Not Glass], Galaxy S8 Wet Applied Screen Protector BUBBLE-FREE for Samsung Galaxy S8 (2017) sitting next to this one, and have gone through both boxes. They look identical to me, so I figured if you are interested in this new kind of screen protector, use this link , and read my previous post. I believe the only difference it the S8, and the S8+.
To actually find this product, it is on the Amazon link, at the bottom of the post. It does come with a lifetime no hassle warranty.
I did receive it for free, and wanted to let you know that it is available.
