Asking opinions.

Does anyone else get tired of posting their opinion on someone’s test only to be told that it’s just you that doesn’t see it? I’ve posted several times that sadly I can’t see the line on someone’s test, only to get their reply that it’s because my phone brightness isn’t up or I have to squint at it or do something else for me to see it. Why post for people’s input if you are just gonna tell them they are wrong?
