In the Stack Exchange Android app I tried to flag a question as a better fit for another site. However, I only got the meta site of the current site, Stack Overflow, Super User and Server Fault to choose from. It would've been a great fit on Unix/Linux, but Server Fault kind of worked too.
Is this four-sites limit intentional? Does it have anything to do with my reputation points?
(Tagged as bug because that was the only thing I was quick enough to read before the error message disappeared. And then I got stuck on the rate limit when I clicked again. Please retag.)
