Thought you guys would appreciate this! - I just recently picked up an iPad Pro 12.9 4th Get (2020) from eBay for a BARGAIN £215 as it had a cracked screen... to be fair it was pretty badly cracked!!.. I then managed to bag myself a brand new replacement screen and installed this a couple of weeks ago (along with a screen protector!) - I've fully tested it now and all functions work as expected - Face ID, cameras, wifi, bluetooth etc! - I use it in sidecar and universal control (depending on what I'm doing) with my 27" iMac - which gives me a little more real estate when working from home.
