Earlier in this thread, there was a customer with this issue but it was resolved when he switched from his 3rd party case to the official Apple case. Both you and another customer are currently having an issue with the official Apple case applied. The other customer's issue was resolved when he removed the Apple case, is it the same for you?
As you might expect, we've sold quite a few packs for 11" and 12.9" by now. The overwhelming majority of our customers seem to have no issues with our protectors with those devices (whereas most of those customers had all experienced issues with other brands, which was how they found us). It does seem though like a very small proportion of customers are having these issues you describe.
I think there's been enough feedback by now in this thread to suggest that these new iPad Pro models are not being made in a consistent manner and that if you were to swap for another iPad, there's a good chance it'll work when using their official case and our screen protector. I believe this specific issue will magically resolve itself on the iPads that are produced over the next few months, as probably this thread is being closely monitored by you-know-who. I also think there's been enough feedback to suggest that it's best to use the official Apple cases because (for the next few months, at least), they're likely the only cases containing a properly-compatible magnet array. As I've shown in the photos of some of my previous posts, the iPad Pros and their official cases are crazy-complicated underneath the surface. Perhaps the cases with no magnets in them will be ok (just not with glass protectors).
I am sceptical that existing glass protectors will ever become compatible with these devices, because (even if it can be fixed on the new iPads), it might acknowledge that there was an issue with the launch stock that they then patched for the subsequent production batches. At the moment, there's (probably?) quite a valid argument that they were never designed to have 3rd party screen protectors on them in the first place, supported by the fact that Apple themselves don't sell screen protectors for iPads, whereas they do for the iPhones.
