In this ConstraintLayout tutorial, you’ll learn how to dynamically position UI elements in relation to other elements on the screen and to animate your views.
The chaining part doesn’t work. Also, there is no cycle chain menu as shown in the screenshots.
@abunur Can you please help with this when you get a chance? Thank you - much appreciated! :]
Hi. This beginner tutorial is great, but just need some updates in parts like on section “Aligning the Top Three Icons Horizontally: Using Chains”. The option “Center > Horizontally” is not working anymore, instead you have to select “Right-Clic > Align > Vertical Centers” in order to make this works . Look at the picture. 
@zuyufavnewtmail Thank you for the heads up - much appreciated!
This tutorial is more than six months old so questions are no longer supported at the moment for it. Thank you!
