Hello, i have some problems with excel for example power query formulas don't work this means the formula doesn't show when i work in custom column mode .Or if i open a new excel workbook some times the power pivot ribbon is missing... and a lot strange things. I updated debug my version (office 2019 professional pro) i made repair online and clean uninstall and install again but these problems are still exist. Any suggestions? I really disappointed because i cant work properly. Thanks !
