The network activity indicator is displayed when the app is syncing the data.

When you modified some data in your database (selected some new groups for sync, fixed a typo, …), trigger a sync with the refresh button.

There are no groups in my App!

You need to select in nil which Groups you want to sync by clicking on the "Cloud sync settings" button.

The groups only sync partially.

In that case, click on the refresh pink wheel. If it’s not sufficient trigger a full sync by pressing the pink wheel for two seconds and you will see a 'Full sync' message, click on OK. See a progress bar at the top. Do not quit the App while it syncs. If you have a lot of Groups it will take some time to sync. First the Groups will be listed, then the images will be replaced by a grey shape and when it’s completely done you will see the images.

I have removed a group from syncing, but it still appears in the App.

Click on the refresh pink wheel at the bottom or quit the App to relaunch it.
If you are still having troubles, trigger a full sync by pressing the pink wheel for two seconds and you will see a 'Full sync' message, click on OK. You should see a progress bar at the top. Do not quit the App while it syncs.

The Nil Groups icon has disappeared from the Settings of my device.

Open Settings and quit it. To quit an App or the Settings, press twice the Home button and slide the App towards the top.

I can’t compose an email.

To compose an email using Nil Groups you need Mail to be configured. Go to Settings, Mail, Account and add an Account. If you already have an account and still can’t send an email make sure the Mail icon is green under that account.

I don’t want some images to sync with the App. How do I remove it?

Go to the Images tab in nil and untick “Include in export”.
