Colors - Therapy Coloring Book

My 12 year old daughter has this app. But other “people” (most likely children) can comment on her work and they say horrible and mean things. Cyber bullying is bad on here. She doesn’t have any social media and I didn’t know this app let others comment. It’s not uplifting to hear, “this is a horrible job” or “why would you choose those awful colors”. Kids are just mean. Don’t let your kids be brought down by others mean comments.
