Geotagging on iPad

I have set up a WordPress self hosted blog and installed the geotagging plugin. The plugin works fine and any posts I make from my desktop maching appear with the geotagging element.

I also have the WordPress app on my iPad 2 and can send posts from that with no problem. When I set up access on my iPad it asked if I wanted to enable geotagging and I selected to do so, but I can’t see any way to geotag a post from my iPad. I thought there was supposed to be an extra button for geotagging before posting, but I don’t see one.

Any help, please
