I use ES File Explorer network remote control to act my phone as a FTP server and move files from my computer to the phone and viceversa. I always copied files from my computer and pasted them into the phone remote folder. From a certain amount of weeks, I am experiencing Paste button to be grayied and not be able to use it. From a random and lucky attempt I have found out that it is possible to copy files by making a drag and drop from the computer folder to the remote folder. That is so strange dolphin-16.04.3-1.fc24.x86_64 Reproducible: Always
