Publishing changes to agent not reflecting in staging/production

I can easily see my changes when I "run" the agent on the voiceflow builder screen. I can also see the changes in the "share prototype" feature. But the changes seem not to reflect on our staging site. Also the link we have used in our flow doesn't work on staging. If I paste the code snippet into Console in inspect element it also doesn't work. However, it works in the "share prototype" feature. What could be happening?
