Meta preview changed are not being show

@manasnant - welcome to the community from a fellow user. 

It takes some time for the changes to be picked up by the various applications outside of Typeform. Because we make the change in Typeform, does not mean that the application on the other end has scraped our new meta preview details and updated at their end. 

You will need to check with the other application to see if they have a test/re-index function and how to call that - Twitter, Facebook and LinkedIn have similar issues but they have all published ‘test your card’ links that will force the update at the opposite end from Typeform. 

hope this provides some direction
