OtterBox Alpha Flex Screen Protector for iPhone 13 Pro Max

I bought this screen protector and it came with what looked like an unusual contraption to install. Once I figured it out though, I thought it was ingenious! Delivery was quick, in fact I was still waiting on my phone to arrive. Installing the glass was easy, and straight forward. No bubbles, and it lined up perfectly. However two days later, it appeared as if it slid and had a huge bubble on the side of the screen. I got the squeegee back out and pressed it down again. Then it appeared as if it was misaligned. Had it stretched somehow? Anyway, I pulled it back up and tried again. Now there are two small bubbles and my fingerprint I need to deal with. Very promising, but fell flat in my experience.
