Remove the Configure your app (server configuration provisioning link) section from the mobile guide for app.element.io

[MadLittleMods]

Your use case

What would you like to do?

Remove the Configure your app (server configuration provisioning link) section on https://app.element.io/mobile_guide/. They are redundant on app.element.io because matrix.org and vector.im are already the defaults in Android/iOS apps.

Why would you like to do it?

They are unnecessary steps to worry about and are confusing when you're just trying to view a Matrix room on mobile coming from a matrix.to link.

Does this feature even work anymore? Not on Android element-hq/element-android#5748

Configure does not work on Android ❌

With Element Android installed on the sign in screen.

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

Configure does work on iOS ✅

Press configure	Brings me to the app	Has the custom info filled out as expected

How would you like to achieve it?

Don't show the configure section src/vector/mobile_guide/index.html#L322-L332 if it's using the matrix.org vector.im defaults.

Relevant Android/iOS code (search for mobile.element.io):

• vector-im/element-ios -> Riot/Modules/Application/LegacyAppDelegate.m#L1841-L1845
• vector-im/element-android -> vector/src/main/java/im/vector/app/features/login/LoginConfig.kt#L23-L46

Have you considered any alternatives?

Somehow a re-design to make this less confusing, less clutter, and actually correct for each platform:

• /mobile_guide needs seperate instructions for iOS and Android #19516
• Mobile guide step 2 obscured #11340

Scanning a QR code sounds a lot better although tricky if you're working from the same device: element-hq/element-android#5097

Additional context

These configure instructions are probably more useful for external Element deployments where the homeserver and identity server URL's are set to something custom.
