15 month old not walking yet

FTM here. my little girl is 15 months old now, shes been pulling herself up on furniture and cruising on furniture for a long time now, like since she was 10 months old or so. but she still refuses to let go and walk on her own. she even walks with her hands against the wall, barely hanging on but again refuses to let go. she also refuses to walk with me. everytime i try to hold her hands she immediately sits down. she wont even stand with me holding her hands. i know shes not quite old enough for me to worry about her not walking, just wondering if theres something i can do to encourage her to walk on her own. any suggestions or anyone have a similar problem??
