Hi.Im currently in the end phase of developing my new iOS app. I am using several third party sdk's (Facebook, OneSignal, Bugfender), so user data gets shared with third parties. As the app will be published in the EU as well, the app has to comply with the GDPR. So know, I'm asking myself, whether I am required to ask for the user consent in the app, before those sdk's get active and submit data (OneSignal won't send Data until someone accepted to get push notifications, while for an example the Facebook SDK starts sending data immediately). This third party is in this case collecting user data and is sending it to their servers and my question is now, if the sdk has to be inactive on first launch and if I have to make an "opt int" consent or if its enough, if I edit my privacy policy so that downloading & opening the app is an automatic consent to sending this data to third parties. How should I get my users consent?Thanks and have a great day.

I am currently working on an app wich will preload 3 AVplayers wich are in an array. With preloading I mean, that the first 30 seconds of the video should get loaded before the video gets displayed on the screen. I decided to do the preloading by iterating through the array, playing all players until they are at 30 seconds. As the players are in an array, there is still a pointer wich references to the memory location on wich the video buffer and the already played video is saved. Is it true, that with that solution, the first 30 seconds won't be loaded when I start the players again at 0 seconds, because I already loaded the first 30 seconds.
