This happened sometime ago but I didnt have the time to raise the request here.
After one of the earlier GP premium update, the color palette of read them got reset and now while creating the post, the color palette of read theme shows the default blue palette instead of red which is the default color scheme of read theme.
I am not that technical to confirm what else was reset but if you can suggest what I can do to resolve it then it will be great 🙂
