Twitter is rolling out the ability to edit tweets to Twitter Blue subscribers in Canada, Australia and New Zealand, the social network announced on Monday. The company says the edit button will roll out to Blue subscribers in the U.S. soon, but didn’t provide a specific launch date.

Twitter Blue subscribers in these countries can now edit their tweets for up to 30 minutes after posting. But, users can only edit their tweets five times within this 30-minute time period. It’s possible that Twitter introduced these limits to stop people from abusing the feature by changing content drastically, while still giving users enough time to correct typos or add hashtags.
