And I’m telling you that your “testing” is wrong. Very much so.
Honestly I must be extremely lucky because I haven’t experienced any crashes and bugs and essentially the game works for me as good as the PC version. And I enjoy the Switch Diablo even more and still happy to play it after 8 years on PC. I didn’t even know about the console players outrage until today, when I decided to check the forums. Damn.
Whatever ya say @mrheoden 
Agree to disagree I guess.
Anyway back on topic for the OP, like I said before I never had those issues @paradicsom. Hopefully my suggestions I gave will help you.
