When you see a red dot appearing on the top left, you should know that there have been some changes in your data that you need to apply on your application data.
It is really important that you update your session so that you can always see the relevant products, prices and retailers.
To do that:
1. Go to the menu on the left and tap on Sync centre
2. You can click on the Update button to sync the data from your web showroom to your iPad
If you just updated some data on your web showroom and you don't see the red dot, please click on Check at the right top in the Sync center to see if there are some available updates.
