I have the same problem with only the homepage being indexed, where all my pages where getting indexed before using a sitemap.
Also, as mentioned in an earlier post, there’s no way to make changes to individual pages and if I change any of the customization options and rebuild (including manually adding pages), nothing has changed in the new sitemap. This is version 3.0.3
As is, I can only find this useful for building an initial template to manually modify after making sure the generator is disabled (so the modified XML doesn’t get overwritten). This is assuming that using a sitemap isn’t more detrimental than beneficial for getting your pages indexed properly, which doesn’t seem to be the case. This appears to be a Google issue. No sitemap errors are reported, but only one url is accepted for indexing, the homepage. Not very useful unless you plan to maintain an endlessly scrolling homepage.
