Since enabling Multisite we've run into a few issues:
When trying to open a single post via the mobile version, it acts like it's opening a new page, then all you see is the title, like it is in a category archive or the home page. The box will not expand to show the post. Clicking on Read This Post doesn't work either.
If you turn off the mobile theme via the little button at the bottom, so you can try and read the post on the desktop version of the site, it redirects to a login page.
We do have WP Super Cache on, with the WP Touch enabled, but we've also tried without cache turned on. I've deleted ALL cache, and still having issues.
