Twitter is now in the testing phase of launching the edit button. In the testing phase, employees are testing the ability to edit a tweet a few times within 30 minutes following posting the initial tweet. It will also let you view your edit history of that tweet.
Twitter said the time limit on fixing typos or context is to protect the integrity of the conversation and create a publicly accessible record of what was said. Later in September Twitter Blue subscribers will have early access to the edit feature. The test will be set to a single country first. No word on which country. How do you feel about the time limit on editing your post?
