Form shows spinner forever after entering card details sometimes

General information

• SDK/Library version: 1.43.0
• Environment: Production
• Browser and OS: Both firefox and chrome

Issue description

This just started happening recently on a new product launch. Using the same drop-in configuration as we do for our other products (ref https://pay.jmp.chat/esim-adapter) some users (not every one, but at least one or two every day) report that after entering their card details the form just spins forever. No errors, nothing in the dev console, just keeps the spinner. What could be the issue? This is different users, in different countries, on different computers, in different browsers, on different OS.

It seems that something similar is happening in my case. It loads but payment doesn't work in some cases. It just wont appear.
No errors. Different users, countries, etc..

It started recently. I had lib 1.27. just updated to 1.43.
Sadly I cannot reproduce this by myself.
It is possible that this problem is from somewhere else. But if i find something out then i will post an update here.

I have downgraded to 1.33.0 for the moment to see if it helps, but since I can't reproduce it's hard to know I just need to wait and see if users report errors still or not.

We do use 3DS2 if that matters.

Hmm, downgrading seems to have broken 3ds, resulting in 3DS Incomplete Authentication Lookup error on every transaction

It seems like using 1.33.0 fixed the issue so far as we can tell. We are now trying 1.36.1 to see if we can get better 3DS support while still having payments actually work.

1.37.0 seems better on 3ds, but still has the infinite spin issue for some customers
