When you first started using the web app you might have noticed pulsing green dots that you could click to learn some information about a particular feature - also known as Tips.
If you want to reactivate Tips, you can access them from your Tips List at any time:
You'll automatically be taken to the section you chose and the Tips will appear again.
Remember that Tips don't all appear at the same time so you won't get flooded with them! This means that sometimes when you read one Tip, another Tip will appear after that.
