Abstract
We report on the first Belle II measurements of branching fractions and CP-violating charge asymmetries in charmless decays. We use 34.6 fb from electron-positron collisions collected in 2019 and 2020 at the resonance. The results are compatible with known values and show performance already comparable with Belle.
