Both of those are actionable, thanks.
Fonts: I raised the smallest labels in the account screens from 8px to 9px and the values from 11px to 12px, and that is already live in the browser build. It is a partial fix and I will say so plainly. 8-9px text is used widely across this UI, and doing it properly is a typography pass rather than a tweak. You are the second person to raise it, so it has moved up.
The pixelation I could not reproduce and I would like to. The browser build runs in a 420x840 frame and the art is authored well above that, so at default size it should be downscaling rather than upscaling, which is not usually where blockiness comes from. Were you on desktop or on a phone, and was the frame at its default size or fullscreen? If it looked worse in fullscreen then it is the upscale and I know exactly where to look.
While I was in there I also fixed a map control that had been dead since launch and some account numbers rendering white on a white tile, both from another tester in this thread. A reload gets you all of it.
