Why is there a delay in displaying my Tumblr posts on my blog?

Recently I have noticed that when I re-blog a post using my iPhone app the post does not display to my blog immediately. The delay is anywhere from minutes to hours before it will show on the blog. I do not have my page set to queue the posts or post them later and I'm clicking on "publish now".

Generally I have a weak signal in my workplace. Could this be the problem? Or could it be the app? I have tried updating the app but the problem still exists.

I maintain a Tumblr blog for a personal business so I sneak onto it frequently throughout the day. I'm wondering if the weak signal is the issue. Anyone else have similar delays? I'd like my posts to display as I post them as they are related to my business.

Is the iPhone 5 battery as bad as people say it is?
