Hello,
We have created several excel sheets which we then move to become sharepoint files. Each user has created their own sheet view in any given file, and is supposed to work in their view, as there can be 2-4 of us in the sheet at the same time. We each apply our own hidden columns and filters to the file for the part we are working in. Randomly, while working, the sheet will just unhide all columns or unfilter itself in sheet view. This happens to each of us. Even if we choose to edit in Excel and not in sharepoint, it happens. Sharepoint defaults to Microsoft Edge office 365 excel app. How do we stop this from happening? It is super frustrating.
