Sometimes after completing a question, I try tapping on an unknown word in a sentence out of curiosity. Sometimes, I get a popup message saying “long press for more information”. Sometimes, when I long press, I actually get more info!
Notice the 3x “sometimes” above. Even immediately after it works successfully, when I return to the question, I cannot for the life of me seem to trigger it again. Am I doing something wrong? I know how to long press, FWIW.
