Excel 365 Sheet Views are not working

NikolinoDE I am having the same issue with these views not working after a day or two, even if I leave the file open, and I am using XLSX format. Filters usually disappear overnight. I leave the file open all the time and sometimes when I come back, the filters are simply not showing and the sheet views stop working. Even if I turn filters back on, all the sheet views no longer function. This is extremely annoying. I wonder if it has something to do with the fact that some people are opening the file through Teams. I have tried to break it by opening in Teams myself, but it doesn't seem to have an immediate effect. My guess is that a series of things together is causing this but I can't figure out what. Probably the solution would be to move this to a SharePoint list.
