no remote management - FTP server - after Android 6 update?

Hi,

I have two A7010a48 (3GB ram) phones and decided to fully update one of them, because of sudden "wifi connect but no inteet" problem..

I scrolled through all of main applications I need and use often, to find out, if this update is worth it, BUT

it seems the possibility to tu on simple FTP sharing has been removed from the file browser!

this is one of the main reasons I bought this phone for, simple file management..

guide me through this please.
