Endpoint Access, Is this an issue with the script or with Twitter changing something?

[stephen-calm]

status = api.PostUpdate('I love python-twitter!')

twitter.error.TwitterError: [{'message': 'You currently have access to a subset of Twitter API v2 endpoints and limited v1.1 endpoints (e.g. media post, oauth) only. If you need access to this endpoint, you may need a different access level. You can learn more here: https://developer.twitter.com/en/portal/product', 'code': 453}]

May your code is not wrong, I've been same issue, but it's about Twitter's API since if your check this link, you will see that you have to pay to get new environments for your App is working.
It's my app but it's free so if you see:

And my endpoints (free plan):

So if my code is this, it'll be same issue

api = tweepy.API(auth)
statuses = api.home_timeline()
for status in statuses:
    print(statuses.user.screen_name)

Seems like the 1.1 API to post tweets is not a free API anymore, we should switch to the v2 API:

They published an example, the interesting part is after line 51:
