Abstract: Talk at QWG 2024. The report presents the latest Belle-II results obtained based on the scan data above Y(4S). The results confirm the existence of Y(10753), previously discovered by Belle. The properties of this quarkonium are discussed in comparison with the predictions of various theoretical models. The report also presents new results on measuring the cross sections of two body B(*)B(*) final states. A hypothesis has been suggested about the existence of a molecular-like state of bottomomonium near the threshold B*B* production.
