[iOS] Switch component loses liquid glass effect when parent is not subject to view recycling

[t0maboro]

Description

Following the discussions in https://github.com/facebook/react-native/issues/54497 and https://github.com/software-mansion/react-native-screens/issues/3392, I was able to reproduce it using a custom native component with view recycling disabled.

I'm opening this issue as a follow-up for further investigation with a reproduction in the reproducer app.

Steps to reproduce

1. Clone https://github.com/t0maboro/Repro3392# and use the latest version from main branch
2. Run the application on iOS
3. Navigate forward -> back -> forward
4. Then toggle the Switch component - the liquid glass has disappeared

cc @cipolleschi as you should have context on Liquid Glass + Switch

[cipolleschi]

added to our queue of iOS 26 issues. I don't have a good answer right now, the behavior is very weird, and it has to do with recycling or how we pool the components. I have to spend more time investigating it.

@t0maboro thanks for reporting it!

[ahmedawaad1804]

@cipolleschi affect our app also, need solution please :/

[IEPiXI]

Also interested in a solution! Any ideas if this will be resolved any time soon? My app is also affected by this.

[ahmed-sudowrite]

I've been able to reproduce this on other components as well, not just the switch- any glass view actually

I also came up against this issue recently. I'm pretty new to react and app development (so I don't have any insight into why) but happy to help wherever I can.

I'm using expo, and created this repository for testing (I logged an issue in the expo github originally thinking it was something to do with expo router, but it's not?).

Let me know if I can help debug the issue at all (with my limited knowledge).
