On Jessie I could "browse device" and transfer/move files to/on/from my tablet.
After upgrading to Stretch I go the message: Failed to launch the file browser. The specified location is not supported. You can enter an alternate browser in the service settings. I have looked through the files in /etc/bluetooth, but could not find any setting referring to a browser. I am using XFCE4 and have also caja installed. Help to solve this problem will be appreciated. Regards Johann -- Because experiencing your loyal love is better than life itself, my lips will praise you. (Psalm 63:3)
