Changing languages and searching within communities

Hey there, is it possible to change the language memmy uses to something other than what my phone’s OS is set to?

I have an iPhone, my iOS is set to German, but I don’t necessarily like the German localization of memmy (no offense to whoever’s involved in that). Usually, the newer iOS versions let you change the preferred language of individual apps separately from the system language. That’s not possible for memmy (yet?). Maybe I missed something in memmy’s settings?

Another question that somewhat relates to that: Can I search within specific communities rather than the entirety of all instances? I wanted to search the memmy community for questions similar to mine, but as far as I can tell I can only search for communities or posts, but not posts inside specific communities.

Thanks!
