Where is the trends (#) icon on new Twitter mobile?

Help me figure this out please!

Is it like a secret game cheat hidden until I do a sequence? Like say find and follow someone who has a Hermit The Frog on a bike profile pic, tap it, long tap it, tap it, tap it, voila!

Is it just temporarily disabled until something is fixed?

No room for one more icon on that neat top bar?

Am I a B case on a A/B testing project?

I really just need to go with the flow and install the app?
