Do you think I did the right thing?

I help out my daughter a lot with my granddaughter, she is 10. She started to be withdrawn and literally ignored me the whole time she is over. I looked in her phone and it looks like the other grandmother has pitted her against me. “ Ooo, she’s upset, black sheep bahahhh” let’s take her birthday “ “ happy birthday “ this is affecting my relationship with my granddaughter which worse, it’s unhealthy. So, I told my daughter and my daughter basically told me I had to figure out a way with it. so, I did for awhile until last night , it’s only getting worse. I told my daughter , she doesn't want to be here anymore and you won’t stop the problem. I can’t keep seeing her like this , it’s heart wrenching to me. I will bring all her toys over to you. My daughter says “ Ok” . I don’t know what else to do. Did I do the right thing: I’ve asked and asked and they are all laughing at me.
