Yeah, I agree that it can be difficult to find an iPad Pro case that doesn’t cater to Apple Pencil users.
I have a 12.9″ iPad Pro (2018) model since its release. I used a Supcase Unicorn Beetle Pro Series case with it for 6 years or so and it had no provisions for the Apple Pencil. IMO a case is structurally compromised if it has to account for Pencil wireless charging sort of like the new iPhone photo button / slider thing.
I just bought a new 13″ M4 iPad Pro and went for yet another Supcase Unicorn Beetle Pro case since it performed so well for so long. Unfortunately I couldn’t find a model that doesn’t have an Apple Pencil so there is this big empty space in the case,…..almost like a handle,……like for a child’s tablet,….
