Prusa's satin sheet is flaking

I've owned a prusa i3mk3 for a number of years and been a huge fan of the platform and company, but today I'm pretty pissed off.

I bought a one of their new satin sheets and some pc blend. The sheet had some slight discoloration which I'm told is normal. After 3 prints the sheet has started to flake off. I used a copious amount of glue... waited for the part to fully cool and used no tools during removal.

The response from their warranty department was polite but underwhelming. I'll paraphrase but they basically told me, "This isn't our problem you must have not used enough glue", go pound sand. I used enough glue, your brand new sheet failed after 3 prints... and you refuse to stand behind it.

Anyone else run into issues with the satin sheets flaking?
