Hello, I had a crash which is on the main thread. 0 CoreFoundation __exceptionPreprocess 1 objc_exception_throw 2 CoreFoundation -[NSCache init] 3 UIKitCore -[UIView(Internal) _addSubview:positioned:relativeTo:] 4 UIKitCore __53-[_UINavigationParallaxTransition animateTransition:]_block_invoke_2 5 UIKitCore +[UIView(Animation) performWithoutAnimation:] 6 UIKitCore __53-[_UINavigationParallaxTransition animateTransition:]_block_invoke 7 UIKitCore +[UIView(Internal) _performBlockDelayingTriggeringResponderEvents:] 8 UIKitCore -[_UINavigationParallaxTransition animateTransition:] 9 UIKitCore -[UINavigationController _startCustomTransition:] 10 UIKitCore -[UINavigationController _startDeferredTransitionIfNeeded:] 11 UIKitCore -[UINavigationController __viewWillLayoutSubviews] 12 UIKitCore -[UILayoutContainerView layoutSubviews] 13 UIKitCore -[UIView(CALayerDelegate) layoutSublayersOfLayer:] 14 QuartzCore -[CALayer layoutSublayers] 15 QuartzCore CA::Layer::layout_if_needed(CA::Transaction*) 16 QuartzCore CA::Context::commit_transaction(CA::Transaction*) 17 QuartzCore CA::Transaction::commit() 18 QuartzCore CA::Transaction::observer_callback(__CFRunLoopObserver*, unsigned long, void*) It looks like that when UINavigationController is animating , another push operation is running. So the error may looks like : navigationController?.pushViewController(vc1, animated: true) navigationController?.pushViewController(vc2, animated: true) Our users have this crash, mainly on iOS 12, 13, 14, without iOS15. We have tested it on Xcode13.x , the crash of attached images will not appear in continuous PushViewController. But we found that : the second push operation seems to be slower. It feels like the second push is performed after the first push animation. So I would like to ask, on iOS15, is there any special treatment for multiple consecutive pushes? Thanks.

Hello, all. Development environment: xcode14.3 + iOS16.4 + iphone12 mini When I use multiTokenContexts to complete the multi-merchant payment function, it prompts "Try Different Payment Method". But if I just perform the payment function of a single order, the payment process can be completed normally. So I would like to ask, is there any limitation to use multiTokenContexts? Thank you, looking forward to your reply.
