These badges indicate the status of your Insync
The blue badge with two arrows means Insync is currently syncing. If the badge is on a folder, it means the folder is still syncing.
The green badge with a check means that your files have already synced.
The yellow check can mean two things:
You migrated and re-used your 1.x folder (as explained in our Migration Guide). Yellow checks mean these were previously synced in 1.x. When you expand the top-level folders, the contents will still have green checks on them if you selected all of them to sync.
If you only synced some items under a top-level folder (partial syncing).
The red "!" on your Insync icon means you have pending items within your Actions, Conflicts, or Errors tabs. If there are unresolved items, you may report them to firstname.lastname@example.org.
BLUE DOT ON HOME BUTTON
This means you have recent changes logged in your Feed. No action needs to be taken. If you want to remove this blue dot, simply go to your Feed to see the changes.
