Android mobile site not working properly

[MyNameIsSuz]

I can access the desktop site on my phone but this isn't ideal, when I access the mobile site it's a really basic plain text version with all menus exposed in full so impossible to locate content or navigate, and if I do manage it I can't post a reply at all - I can write one, but the post and preview buttons do nothing. Is there a way to solve this? It's been like this since yesterday or maybe the day before.

Oh, and it's an Amazon fire phone I have, so I can't get the app as they don't have it in the amazon store yet.
