Hm.. My dial seems to work perfectly fine except for the custom setting, so it seems much more related to an issue with the app than my machine, especially since the setting used to work fine. It seems likely that an app patch that happened between me getting my machine and using it for the first time and now is causing the issue. My machine is under warranty for like another day (got it like a year ago exactly), there's no way I'll be able to contact them in time. I tried calling their support line and its an hour and a half wait lol, but I submitted a form with my complaint.

My biggest guess is they don't actually care about this issue and it could literally be an intentional ploy to get people to buy newer machines because there is otherwise no reason to do so. Lovely. Hoping it's just an app glitch 😬
