Managed Permissions not retaining after app update

Thanks, as mentioned previously, this is not ideal at all as it will cause our appspace to explode with apps, also causing our end users headaches in trying to locate the correct app to use for their report viewing.  Has there been any discussion to allow creation of a folder structure within the appspace?  i.e. HR app with multiple sub folders underneath which could then correlate to the unique viewing audiences.  Or is it possible to control those permissions within row level security directly in the PBIX desktop created report? Not having the abilty to control permissions at a lower level than app is not going to work.

Thanks.
