First pic is the main front display - it’s not full screen theres black bars to the left and right
Second pic is opened display - i just think monzo design team can do a bit better than this. It looks super ■■■■, it’s just been stretched. Something like tiles or management none side and balances on the other? There’s a lot more room to play with so why am I scrolling?
Large screen device support is part of @davidwalton findings within the apps code recently. Monzo just need to activate it, unless this is it already, and it’s terrible.
