Unfortunately, on android facebook purposefully disables parts of the website (chat in particular) to force oyu to install the app.

Chat is also disabled in the app. You have to download Facebook Messenger to get it.

I suspect that decision to split the app comes from equal parts marketing and software engineering incompetence.

Chat can still be accessed through mbasic.facebook.com.

What other parts are disabled?

That's intentionally awkward. If I tap the messages icon on Facebook.com on mobile, I get redirected to a page telling me to download the app. Similarly, messenger.com points me to the App Store.

I didn't know about that website. Thanks.

On the contrary: You can even enable push notifications with Chrome for Android. Chat included. I haven't touched the native apps for ages and everything works just fine.
