Well I don't know if she was popular among the Swedes or not, I have never heard that she was not liked either. The only thing I have heard is that the relationship between Ingrid and Louise was rather difficult. The reason was that teenager Ingrid was used to being the only female in the family and she saw her new stephmother as an intruder, or something simular. Not very uncommon for a stephdaughter to have that opinion IMHO. The relationship improved when Ingrid was more mature and (and left for Copenhagen

), but still both women had very different characters. I have never heard that any of the boys had particular difficulties with their stephmother though, the relationship seems to have been cordial at the very least.
