Hi! I just read you post about the trouble you're having. I think it might be your browser. I used to have Safari and so many things did not work for me on Tumblr. I download Chrome and now Tumblr works great. So, it might be that you need a new browser. I hope this helps. I hope you can figure out the problem. Good luck!
Yeah I think this is the problem too. However the latest versions of every browser are no longer compatible with my mac version, so I’m taking it to a “genius” on Monday. Fingers crossed I can resolve this disruption of Sunny! (Answering again from my iPhone…)
