Platform Notes#

Short, focused notes on platform-specific quirks and configuration requirements — AutoFill, browser scopes, and queries plist on iOS; cookie management and manifest flags on Android; toolchain and deep-link setup on React Native. Use these alongside the relevant Layer or How-To pages.

These are short reads. Each platform-notes page lists 4–6 self-contained items. Skim the relevant page when something looks off at the OS level (deep-link routing, autofill, attestation on simulators) — most “this works in dev but not in TestFlight” issues live here.
