iOS handle deeplink from push notification not working

[EstevaoCoelhoRobbin]

Related: https://github.com/customerio/customerio-flutter/issues/35

Using a iOS device when I click in push notification, app is opened but don't navigate to deeplink. Using a Android device works normally. It's an Flutter App, using customer_io: ^1.3.1 version:

All other things like push status tracking are working normally.

here is my ios/Podfile:

platform :ios, '13.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

target 'Runner' do

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  target 'RunnerTests' do
    inherit! :search_paths
  end
end

  installer.pods_project.targets.each do |target|

        if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 12.0
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      end
    end
  end
end

        // Remember to modify the siteId and apiKey with your own values.
        // let siteId = "YOUR SITE ID HERE"

we are affected in this bug too

I have the same issue

[levibostian]

Thank you everyone who reported this to us and provided all these great. Sorry to hear you have experienced this issue.

Based on the information provided, this appears to be a new issue that we are currently aware of and are in the process of fixing. To help us diagnose the problem more accurately, could you please send your SDK debug logs to win@customer.io? Be sure to capture all of the logs starting from when the app opens through when a push is received and clicked in your app.

As a temporary workaround, we recommend removing FlutterFire from your app and using only the Customer.io SDK to receive push notifications. We understand that this may not be the most convenient solution, but please be assured that we are actively working on a permanent fix for this issue.

Thank you for your patience and cooperation.

Oh, and disregard the status of this ticket as "not planned". That's for internal tracking, only. We are aware of this issue and will keep you updated on it.

Bug fix is in production.

Follow these docs to update the SDK version and make new builds of your app. Be sure to follow all of the steps in that doc, not just the Flutter pubspec step.

Thank you again for reporting this to us. Hope the new version fixes your issue. Come back to us if it doesn't.
