So I just installed Ubuntu 17.10 and everything seems to be working fine, but there is a little problem. When there is an app, that should have an app indicator, it is nowhere to be found. In previous versions, it was located in the top right, along with the power off menu. In Ubuntu GNOME, they were located in the bottom left.
I have tried installing two different extensions, but none of them seems to work. I tried these: https://extensions.gnome.org/extension/1031/topicons/ https://extensions.gnome.org/extension/615/appindicator-support/
