Hello all!
Could you please run these:
sed -i 's/insync start/insync start --qt-qpa-platform=wayland/g' ~/.config/autostart/insync.desktop
sudo sed -i 's/insync start/insync start --qt-qpa-platform=wayland/g' /usr/share/applications/insync.desktop
As per our engineer, this would be the fix in order to run Insync as expected.
