Not walking yet

My LO turned a year on May 6th. She crawls all over the place, pulls herself up on everything, cruises around holding onto the furniture and can climb stairs and pull herself up on the couch and everything so she is very active. She has absolutely no interest in standing on her own or trying to walk. I know that it can be normal for babies not to walk up to 18 months but my concern is that I can’t get her to stand at all. When I try to hold her up holding her arms to stand or walk she will just tuck her legs in and collapse to the floor. She has the ability but just really has no interest in it and has been like this for 3 months now. I’m worried she won’t learn to walk because she just refuses to try. Anyone else go through this?
