Multiple landing pages are used when elements on a page are replaced depending on certain parameters. For example, the content on the page can vary based on the geographical data, i.e. on the location of the user. Use the block T804 or T810 from the “Other” category.
If you have added your city but still cannot see the block you need, we recommend that you check the way Tilda determines your location: http://geo.tildacdn.com/geo/full.
