Did you know that you can turn on icons in your Ancestry family tree that connect to your DNA results? Click on the DNA icon at the bottom of the tree management icons on the left and a panel will swing in from the right (as in the image below) showing three icons that you can turn on: ThruLines, Possible DNA Matches, and Connected DNA Matches. Just click the On/Off slider to turn each of them on or off. 
UPDATE 24-Jan-2022: The icon has been turned slightly sideways and now looks like the one on the left here:
Turning on the DNA Discoveries Icons – red arrow showing where to click is my addition
Of all those, I find the ThruLines icon the most useful because when looking at the boxes view in a complicated tree, I can easily pick out my ancestors because of the little blue ThruLines icons (as in the example above). Since my brother has tested, all my direct ancestors back to my 5th grandparents have that icon. In the past I had put my own icon in the suffix field. Then I used the direct DNA ancestor tag that Ancestry provides. It is so much less work having it done automatically for me!
Clicking on a profile with the ThruLines icon pops up a box with a summary of information about that person including, on the bottom, the word ThruLines with a down arrow to the right of it. Click either the down arrow or those words to expand the little window downwards, as shown on the left. and see clickable green highlighted words that will take you to the actual ThruLines page for that ancestor (example below).
