It looks like some network specific on your side because if I check on my computer I see that everything is loaded within an example time. Also if serving the Stripe/js library is slow I would recommend to reach out to Stripe customer support there.

Since we are not Stripe itself and there is little we can do here

I’ve tested this myself, and the issue occurs 2 out of 5 times. This is concerning for end users trying to log into our web application, as they see a white screen and end up closing the browser.

Is there anything we can do on our end to ensure this never happens?

I reached out to Stripe customer support, but they mentioned there was little they could do since this is a Flutter Stripe-specific issue. That’s why I’m reaching out to you.
