My app package download stuck at 0% , this for all packages and all PC . Using SCCM 1902 , Client is Win7, Win8.1, Win10. The issue persist on all computers. The pkg successfully distributed to the DP. Another strange thing is , each and every computer needs to be approved in the SCCM console after client installation thn only it turns green else the console shows the client as unknown(with question mark).
