I have a 5th gen (M1) iPad pro 11" and I'm looking for a replacement case for my look-alike Smart Folio case byTimovo that I got from Amazon (magnetic front and back, no pencil flap). The Apple Store link says the Apple one is compatible with the 4th gen iPad pro but does not mention the 5th:

The BestBuy description for this item says it's compatible with 3rd-4th gen. The Amazon description says 3rd gen. I have yet to see any link that says it's compatible with 5th gen, even at Apple. If I go to Apple's own app on my iPad, and I go to look for accessories for this device, they point me to the 4th gen case. Another Apple link claims this 4th gen case is compatible with 1st-4th gen iPad Pro 11:

[https://support.apple.com/en-us/HT204158#:~:text=iPad%20Pro%2011%2Dinch%20(1st,iPad%20Air%20(5th%20generation)](https://support.apple.com/en-us/HT204158#:~:text=iPad%20Pro%2011%2Dinch%20(1st,iPad%20Air%20(5th%20generation)](https://support.apple.com/en-us/HT204158#:~:text=iPad%20Pro%2011%2Dinch%20(1st,iPad%20Air%20(5th%20generation)))

Why is there no folio case listed as compatible with the M1 (5th gen) iPad pro, or 6th gen for that matter? I'm pretty sure it will work with my 5th since it's mechanically similar to the 4th iPad Pro, but I'm curious why they don't list support.

Also, my Timovo case held up for 2.5 years before the edges started fraying, and the front and back still look in excellent condition. Should I expect the Apple one to last even longer? Reviews claim that the Apple case feels more premium than the much cheaper Amazon cases.
