should this actually be ANDROID_JAVA_UI?

I've asked, and both dfalcantara and tedchoc agree with OS_ANDROID at this
point.

   // Determine if we are in a valid context (on desktop platforms, we could be
   // in an app window with no Browser).
   if (!chrome::FindBrowserWithWebContents(web_contents()))
     return false;
 #endif
 
   return signin::ShouldShowPromo(
       Profile::FromBrowserContext(web_contents()->GetBrowserContext()));
 }
 
 void ChromeAutofillClient::StartSigninFlow() {
-// See ShouldShowSigninPromo.
-#if defined(OS_IOS)
-  return;
-#elif defined(OS_ANDROID)
+#if defined(OS_ANDROID)
   chrome::android::SigninPromoUtilAndroid::StartAccountSigninActivityForPromo(
       content::ContentViewCore::FromWebContents(web_contents()),
       signin_metrics::AccessPoint::ACCESS_POINT_AUTOFILL_DROPDOWN);
