Unable to double tap on the trackpad to highlight multiple words in macOS Mojave

In previous versions of OS X, I was able to "double tap" on the trackpad and then move my finger to the side or down to highlight/select text/multiple text.

I'm unable to duplicate this in the new macOS Mojave. Previously, I'd enable System Preferences > Trackpad > "Tap to click". Any ideas?


Although not specific to Mojave, this link helped me out.

System Preferences > Accessibility > Mouse & Trackpad > Trackpad Options > "Enable dragging" [without drag lock]. enter image description here
