Tripadvisor mail pagination

Hello Everyone,

I have been trying to scrape restaurants' emails from Tripadvisor. So far, I have manage to scrape the first 30 emails corresponding to the first 30 restaurants on the first page. Nothing is scraped from pages 2,3 and so on.

There are similar posts in the forum that I've tested them but they don't seem to work.

They all seem to run in the beginning but after a while they stopped and nothing is scraped.

Thank you for helping me out.

ps : Is there a way to limit the number of pages scraped ? Let's say to 15, for example ?

Start URL :

Sitemap: This one extracts the first 30 restaurants from first page.

{"_id":"tripmadrid","startUrl":[""],"selectors":[{"id":"Restaurant","type":"SelectorLink","parentSelectors":["_root"],"selector":"a._15_ydu6b","multiple":true,"delay":0},{"id":"mail","type":"SelectorLink","parentSelectors":["nombreresto"],"selector":"div._36TL14Jn:nth-of-type(2) a","multiple":false,"delay":0}]}
