Can not overwrite *.pbix file on PBIRS who was made diferent user

[Honzav]

Hallo,

Can I have a questition? Why can I not overwrite *.pbix file on PBIRS* who was made by diferent user? I´am member of system administrators group on site settings and member of group, who have content manager permission on all foldes (+ content manager on *.pbix file).

I tried PBI desktop* "save as" -> "Report server" -> select existing report -> "overwrite" .. result: "Sorry, you don´t have permission to save in this folder. Please choose a different folder and try again"

I tried it from the portal through the "Replace" button, the same result.

But, when I save the same report from a PBI desktop under a different file name, in the same folder, I can already overwrite it. Why not from other user?
