Hello,
We are encountering an important issue related to the multi touch on the iOS 13 Beta version.
Here is the case: we have a music application where the user has to touch the screen with 3 fingers at approximatively the same time.
Since we updated our test devices on iOS 13, we've seen that only 2 touch maximum are detected.
We have the same issue on our other music apps where the user has to do the same thing.
Thank you for your help,
