‼️ Bubble started serving a wrong CSS that broke my app on iPads?

Since this morning (CET), I have been experiencing a critical issue with my app, ShopFan, which is built on Bubble.io and wrapped using BDK Native.

Issue Description:
The app works fine on iPhones and Android devices.
However, on iPads, when opening the native app (which loads https://app.shopfan.io/mobile in a WebView), the screen stays black. I have loads of clients calling me because the app gives a black screen on iPads.

I inspected the issue using Safari’s Web Inspector and found that a CSS file is failing to load with a 400 error.

https://app.shopfan.io/package/run_css/a44635d587000506802db465e8554d6eafa9c50356e052c9298df9a9df722bbc/shopfan/live/mobile/xfalse/xfalse/reset.css.map

the answer is
{"error_class":"ClientError","args":{"code":"1742465332215x199013686289149400"},"message":"Invalid request: see error code for details"}

Additionally, there is a 404 error for a JavaScript source map file hosted on jsDelivr, but I assume this is not critical.

Troubleshooting Steps Taken

I tested the same URL (/mobile) in Safari on iPad, and the same 400 error appears in the console.
The issue does not occur on iPhones, suggesting it might be specific to WebKit on iPads or how Bubble serves CSS for certain devices.
The iPad has not been updated recently, and no changes have been made to my Bubble app in the last few days.
Clearing the cache and reinstalling the app did not solve the issue.

Questions for Bubble Support or the community

Has Bubble made any changes to how CSS files are served?
Are there known issues with WebView on iPads, especially with Safari 18.3?
Is there a way to force a reload of CSS files or serve them differently?

This is a major issue for my users on iPads, and I would appreciate any guidance on how to resolve it as soon as possible.

Thank you for your help!

My users also started complaining about this on iPads using web view.
