My Company has an iOS app which used the old parse.com service to send notifications using a php client. We have since bought a new app but some of our customers have decided to not upgrade to the new platform. What is the simplest way for me to repair the push functionality?
I hope this makes sense. I am a front-end developer usually, with not much experience but this has kind of become my responsibility. One thing to note is I don't actually have access to the native code of the app at the moment. Would I be able to fix this without making any changes to the code of the app?
