When you edit the content of your Persistent menu, sometimes those changes aren’t shown in your page’s inbox right away. This is due to the fact that the Facebook cache gets refreshed only periodically.
What you can do to speed up the process is disconnect the page from your bot and then connect it again.
Before testing again, first delete the conversation with the bot from your personal inbox. That will enable your local cache to get refreshed as well.
Also, keep in mind that each of the localization options in your Persistent menu needs to be edited separately. What you need to do is click on the language tab and edit this specific version of the menu items.
The menu language localization is displayed based on the language each person is using in their Facebook settings.
In the case from the screenshot above, people using their Facebook in English will see this version of the menu, the ones using French will see that one, and everyone else will see the "All other languages" option. You can have as many or as few options you want here.
If you’ve attempted these solutions, and your Persistent menu doesn’t seem updated - reach out to support and we'll look into the issue.
