Configure link to define custom homeserver/identity server automatically from `https://app.element.io/mobile_guide/` does not work (`mobile.element.io`)

[MadLittleMods]

Steps to reproduce

1. Have Element Android installed and signed out
2. Visit https://app.element.io/mobile_guide/
3. Click the Configure button
4. Notice how it just redirects to https://mobile.element.io/?hs_url=https%3A%2F%2Fmatrix-client.matrix.org%2F&is_url=https%3A%2F%2Fvector.im%2F instead of being handled by the Android app

---

With Element Android installed on the sign in screen.

Press configure	Just redirects me to mobile.element.io and pressing "Try again" does nothing

Outcome

What did you expect?

The Android app opens with the custom homeserver and identity server filled in

What happened instead?

Just redirects to https://mobile.element.io/?hs_url=https%3A%2F%2Fmatrix-client.matrix.org%2F&is_url=https%3A%2F%2Fvector.im%2F which tells me to update my app (which is already the latest) and try again which also does nothing.
