Selenium doesn't scrape tweet ids

Imagine you are in this twitter page and you have to take all of its ids! https://twitter.com/search?l=fr&q=%23metoo%20since%3A2017-11-06%20until%3A2017-11-09&src=typd

I am using selenium to scroll down until there are no more left and then save all ids in a list.

Im afraid my for loop doesn't save them though, what am I doing wrong?

twitter_ids_filename = 'all_ids.json'
id_selector = '.time a.tweet-timestamp'
tweet_selector = 'li.js-stream-item'
ids = []

for day in range(days):
    d1 = format_day(increment_day(start, 0))
    d2 = format_day(increment_day(start, 1))
    url = form_url(d1, d2)
    print(url)
    print(d1)
    driver.get(url)
    sleep(delay)

try:
    found_tweets = driver.find_elements_by_css_selector(tweet_selector)
    increment = 10

    while len(found_tweets) >= increment:
        print('scrolling down to load more tweets')
        driver.execute_script('window.scrollTo(0, document.body.scrollHeight);')
        sleep(delay)
        found_tweets = driver.find_elements_by_css_selector(tweet_selector)
        increment += 10

    print('{} tweets found, {} total'.format(len(found_tweets), len(ids)))

    for tweet in found_tweets:
        try:
            id = tweet.find_element_by_css_selector(id_selector).get_attribute('href').split('/')[-1]
            ids.append(id)
        except StaleElementReferenceException as e:
            print('lost element reference', tweet)

except NoSuchElementException:
    print('no tweets on this day')
