Implementation Plan for #3561

Summary

Enable the multi-account dropdown on the home screen for Level Zero accounts by removing the isAtLeastLevelOne restriction.

Root Cause

The dropdown functionality in home-screen.tsx is gated by an isAtLeastLevelOne check:

<Pressable onPress={isAtLeastLevelOne ? handleSwitchPress : null}>
  <View style={styles.profileContainer}>
    <Text type="p2">{usernameTitle}</Text>
    {isAtLeastLevelOne && <GaloyIcon name={"caret-down"} size={18} />}
  </View>
</Pressable>

For Level Zero accounts, isAtLeastLevelOne is false, which:

1. Sets onPress to null (dropdown tap does nothing)
2. Hides the caret-down arrow icon

This prevents multi-account users with a Level Zero account from switching via the home screen shortcut (though the Settings path still works).

Proposed Approach: Enable for All Authenticated Users

Complexity: Simple

Changes required:

• app/screens/home-screen/home-screen.tsx:459-465:
  • Change isAtLeastLevelOne ? handleSwitchPress : null to handleSwitchPress
  • Change {isAtLeastLevelOne && <GaloyIcon ...>} to always show the icon (or use isAuthed)

Proposed code:

<Pressable onPress={handleSwitchPress}>
  <View style={styles.profileContainer}>
    <Text type="p2">{usernameTitle}</Text>
    <GaloyIcon name={"caret-down"} size={18} />
  </View>
</Pressable>

Alternative Approach: Multi-Profile Check

If we want to be more precise and only show the dropdown when user has multiple profiles:

• Create a hook or state to track if user has multiple stored profiles
• Only show dropdown when hasMultipleProfiles === true

This is more complex and may not be necessary since the profile screen already handles single-profile cases gracefully.

Testing Plan

• Manual: Test with a Level Zero account that has multiple profiles stored
• Manual: Verify dropdown arrow appears and tapping navigates to profile screen
• Manual: Verify single-account users can still access profile screen
• Existing tests in __tests__/screens/settings-screen/multi-account.spec.tsx should still pass

Risks & Considerations

• Single-account users will now see a dropdown arrow that leads to profile screen (this is acceptable UX)
• No security implications - this is purely a UI gating issue
• The underlying multi-account functionality already works (via Settings)
