Since Mikrotik updated SMB version, I have issue copying file, the file keep on uploading and after few seconds it halt, and cause error, then I have to hit retry. I first though its for Mikrotik, so I restart it, then I though its for my OS, but now I have same issue on another windows machine as well.
Also I received this SMB update on 7.12 or before that, and since that, I cant use my mobile phone to connect to SMB using `ES Explorer` software... can you provide older version as well or make it switchable?
