Excel 365 Sheet Views are not working

I have a very similar issue. Excel workbook with queries and pivot tables and slicers to create customized reports uses could view and edit in their individual sheet view. This spreadsheet worked during the fall of 2020 but the identical spreadsheet now constantly refreshes the sheet view based on the last user's filter modification. Basically all users have to work with the same (default) sheet view, instead of their personalized sheet view. This eliminates to possibility of multiple users using the spreadsheet independently.
