iPad Air 4 blanks whenever I lay it down

So apparently this is a repeat of an issue that happened on older model iPad, see the thread at

The origin of the problem also seems to be the same, namely the magnetic cover on the case:

… I took my iPad out of my case as it was continually going to sleep with every little movement. It stopped when it was out of the case. I put it back in and it started doing the same thing. I realised this only happens when the cover is wrapped around the back not when it's left open like a book. I then took the case off and just put the magnetic part of the cover behind my iPad roughly where it would be if the case was on and cover was wrapped around the back. It kept going to sleep with any slight movement but only when the magnet was touching the back of the iPad. I'm pretty sure the iPad is sensitive to the magnet part of my cover…

Just wondering if anyone else is having this issue and if they’ve found a solution that doesn’t involve removing the case. I use my iPad for art a lot and it’s a bit of a pain to not be able to fold the cover back, but I’m also an Olympic-class klutz, so going without a protective case is just not an option.
