Just got burned with a 1-star review? Here's what to do.
If the critical review has pointed out an actual, fixable problem, you MAY post a comment after the problem’s been fixed. Identify yourself as the author, noting that as of such-and-such date, the error has been amended. This will let current shoppers know the identified problems are fixed.
For goodness sakes, if you are self-publishing, get an editor and don’t rely on reviewers to point out your errors, figuring you’ll “fix it later if it makes any money.” Way to ruin your career before it gets started.
You may also note in the product description that it’s a new version as of such-and-such date, though only if absolutely necessary, such as if all the reviewers point out your Orcs use the wrong type of toothbrush.
