twitter bot selenium not liking all tweets on the page

I'm learning about selenium on python and came across an error I don`t really know how to solve: In this project the bot I've designed was supossed to Like all the tweets on the page when I searched for a certain subject. Altought the bot go through all the loops and like half of the tweets, it still misses every 2 or 3 tweets. Could somebody shed a light on why is it missing tweets?

#  it's essencial that the user first pip install selenium on his system or on the source code editor such as visual code
#  afterwards download the latest geckodriver on github and unzip it on the root of your python folder
