How to view threads through your Home and profile timelines
A thread from someone you follow with 2 or 3 Tweets will generally appear on your timeline connected by a line to distinguish them as a bundle. When there are 4 or more Tweets in a thread, the Tweets will be truncated, and you’ll see an option to Show this thread. Click or tap this message to expand the full thread.
Threads on your profile timeline will appear as separate Tweets, in reverse chronological order. Each Tweet that is a part of your thread will have an option to Show this thread to view the thread in its entirety.
