    I want to know how to resolve.

    CompornetOne Excel for UWP ver.10.0.20211.739

    VisualStudio 2019 16.10.2

    1. Load from xlsx file exists. This xlsx workbook has DataValidations(List) in a sheet.
    2. I known the validations exist in sheet just before saving workbook using QuickWatch in VisualStudio.
    3. My program call workbook.SaveAsync and this method is done without exceptions.

    But, when I open this saved ExcelWorkbook, there is no validations in sheet.

    I want to resolve this problem.
