Since I started playing with Micro.blog today it became quickly evident that not all themes support it properly. They let you see your posts but if you embed an image for example it won’t let you see it in your WordPress blog.
After reading this it seemed to indicate that only WordPress default themes would properly support it. After testing it I settled on one called Twenty Seventeen that now allows me to see anything I post to Micro.blog appear on my WordPress one.
I’ll need to tweak it but for now I’m happy that my posts are visible.
