I'm not trying to sound rude, but this sounds exactly like the issue with the Pixel 2XL. Someone correct me if I'm wrong, but I don't think the second revision solved anything from the 2XL. As far as I'm aware of, only Whitestone and some other offbra d that used Loca glue were able to make screen protectors for the 2XL.
I feel like this is a common occurrence with your company where you lure people into buying a poorly designed screen protector and promise them that the second revision will be better, thus stopping people from doing early refunds in hopes that it'll be too much effort for them to refund. It sounds super shady. Someone correct me if I'm wrong.
Yes - we can understand your perspective here. intelliARMOR is a USA based company and we run our own production / models for all our glass. We're caught somewhere between being a tiny company and being big enough where Google will "play ball" with us and give us pre-production specs on their devices.
Our fist gen Pixel 2 HD glass did miss the mark as well, however this corrected on the subsequent version that shipped out in December of last year (our time frame for shipping the revamped Pixel 3 glass).
