Yes and no. I mean it's not their job to make sure your daughter is being included outside of the gym but at the same time they were sympathetic to how my DD was fitting in and they gave me insight into the situation (if/when I didn't necessarily understand everything) and they would also help when they could like with group activities and pair up buddies for conditioning, etc.
You don't have to share here if you aren't comfortable, but do you know what the problem is? Age difference? Bullying? Personality mis-match? The worst for my DD was the tween years. She was a couple years older than most of her teammates and she also has a unique personality. This combo created a couple of rough years for her but it worked itself out. She is in her early 20's now and is still BFF's with her gymnastics teammates!
(ETA - I don't want to imply that the problem was all on my DD, or that the problem is all your DD, just that people and relationships are complicated. Also, friendships are going to develop outside of the gym, which is OK. And bullying is not OK and the one time this was happening at my DDs gym I was looking into other gyms for her when the bully abruptly quit. Hopefully you aren't dealing with a bully.)
