Cannot pull all tweets using since_id parameter


HI guys. I have been running a Python code for the past month scraping for a specific term. The only parameter I am amending in the code is the “since_id” and insert the highest ID I have for that term from the past code run. I normally do it once a week. I normally get 15-20MB of data and dates show all 7 days.

My last two runs were unsuccessful. I tried doing it a few ago, but got two days data only. Decided to try today again and it’s even worse - I am getting tweets from today only even though my “since_id” has a Tweet number from 29th July. Has it anything to do with “count” parameter? I tried removing it all together, but still am getting one day’s tweets only.
