Hi Sarahí! I´m Rodrigo
Regarding your issue, as emmanuel says, you have to refresh the information that facebook gets from your app, in this case what you´re going to do is the following:
1) Go to your SEO & Metatags tab, under the preview of the thumbnail you have to click where it says
2)This will send you to the "Object debugger" page of facebook, there you have two buttons "Show information of current extraction" and "retrieve information of the new extraction"
3)You can click on the first button to see what is currently showing on facebook, and on the second button to update the SEO information
Let me know if that works for you
P.S. I actually developed the app "Honeymooning" for Sarahí, if anyone is interested in my services, packages and prices, you can send me an email or chat with me via my page: http://bluflame.xyz
