I had a recent update in my Excel 365 and what I see now is multiple excel sessions open in background. When I go to Task Manager I see a number of these sessions. When I double click on Excel file I get prompted that now my personal macro workbook will be in read only format. It's not only for Excel sessions actually. I also noticed that I get same issue for Chrome. Can somebody please help me what could be the issue and where I should look for help at Microsoft website maybe?
