Hi @charlotte12 The edit option is available for 2 hours after we post a reply. Once the option closed we can’t edit ourselves, but it’s still super easy to have an edit done for you.
Use the same three dots … in the lower right corner.
Click: Report Comment. A new box will open up where you can let a moderator know what changes you’d like to make.
A little tip. Once you open that new box you won’t be able to see the original rely than needs editing. So, when I need to do that, I copy and paste my reply in the box, then make the edit comments from there to show where a word correction is needed or rephrasing, whatever you’d like.

Give it a try and let me know if it doesn’t work out for you.
