The animation was very useful. At a glance you could tell if your files were up to date or if something is still downloading. The indicator, in other words, was indicating something. Please bring it back.
@rahi: When Insync is performing syncing activities the tray icon should change to the blue circle with clockwise directed arrows. It’s the first one on this page: Insync badges guide. It’s not animated anymore but it still indicates that a syncing activity is currently processing. Is this not happening in your case?
@rahi: I see. Are you running the latest version? You can get it from www.insynchq.com/downloads. Also what Linux version and distribution are you using, and what desktop environment?
