Recently upgraded from the 2.0 beta to 3.0. There was no tray icon so I performed a clean install this morning via: insync_3.0.19.40421-bionic_amd64.deb and insync-nemo_3.0.13.40201_all.deb. The problem persists.
Dell XPS 15 9550
Linux Mint 19.2 Cinnamon
sni-qt is installed
Edit: Still no tray icon, but I was able to enable icons in the applications and startup lists by changing “Icon=insync” to “Icon=insync-folder” in the relevant .desktop files. I’m guessing that an icon that was supposed to be bundled in the installation is missing?
