To view hidden replies on Twitter, locate the tweet with hidden replies and click or tap on it to expand the thread. Look for a grayed-out "Hidden replies" icon or text beneath the tweet. Click or tap on this icon or text to reveal the hidden replies. Twitter may hide replies that are deemed inappropriate or irrelevant by the original poster. Revealing hidden replies allows you to see additional perspectives and discussions related to the original tweet. Keep in mind that not all tweets have hidden replies, and the availability of this feature may vary based on individual tweet settings.
