Learn French: Elles ne regardent plus jamais ces plateformes, elles se déconnectent. - They fem. never look at these platforms anymore, they disconnect.

Negative words like plus (anymore) and jamais (never) replace pas. You can stack them together to combine their meanings, creating "never anymore" or "no longer ever". Saying ne regardent pas plus jamais would be a grammatical mistake!

Does the order of plus and jamais matter here?

Yes! When combining negative adverbs in modern French, plus almost always comes before jamais (as well as before rien or personne). While you might see jamais plus in poetry or older literature, ne... plus jamais is the standard rule for everyday French.

Why is it elles se déconnectent and not just elles déconnectent?

The verb se déconnecter (to disconnect/log off) is reflexive when referring to a person logging out of a system or website. You can think of it as "they disconnect themselves." If you just used the non-reflexive elles déconnectent, a French speaker might think they are physically unplugging a device.

When listening, how do I know if it's ces plateformes or ses plateformes?
