I'm getting "Tray icon not found" error message. I'm using .deb version of S3Drive, v1.15.7. It worked last week even on the same S3Drive version, but then suddenly broke. It doesn't work for me even on Windows version btw
Thanks for your report. This is now addressed in a : 1.15.8+2 Windows release and 1.15.8+1 on Linux.
I would appreciate if you could try it and le me know if problem is addressed.
