Why didn't my follower receive the Linksender message, or why isn't the link clickable?
This usually happens when the person doesn't follow you on Instagram — Instagram may route the message to their "Requests" folder instead of their main inbox, and the link may not be clickable until they accept it. This is an Instagram limitation, outside of our control.
Our tip: mention this directly at the bottom of your post caption, along with the correct keyword – that way, your followers know to check their "Requests" folder if they don't see the message right away.
