iPhone Courier/Customer app issues

This freelancer job is to fix two iOS apps that have to communicate with each other. The apps are similar to a delivery application that puts couriers in contact with customers. The API for the apps is working perfectly as we also have two android apps running and they are working fine. The problems we are experiencing with the apps are as follows: Communication Issues: The courier is notified when the customer requests a service. The customer is NOT notified when the courier accepts the job, is on their way, has arrived , etc. etc. (These issues could be related to incorrect setup of MAP Key’s, etc. and/or push notifications???) Want to discuss with the freelancer. The Courier app and the Customer app: Storyboard has the forgot password screens but no links show up to forgot password in the apps! Customer app: When a new customer registers the process should be as follows: Customer creates an account (no issues) The customer can login - however the very first time the customer logs in, he/she should be presented with the Apply Referral Code Screen and after that screen the Display VC Card Screen. The app can not get past the Apply Referral Code Screen. No matter what buttons are pressed, nothing happens. Courier app and customer app: Login with Facebook crashes both the Courier and the Customer app. Customer app - when rotating the kind of service requested, the map does not display the available couriers correctly. Customer app: fair estimate does not display close-by locations! Customer app: payment - adding a credit card crashes the app (Stripe related?) Customer app and courier app - edit profile take a photo and select a photo crashes the apps on my iPhone 6+ running iOS 10.0.1 (does not crash on an iPhone 5s running ios 8.1) (access to camera and image library denied?- it does not ask to access camera and image library in iOS 10.0.1!!)
