Android In-App Webview Subscription flow fails after clicking "Agree & Subscribe"

[red-digital]

As far as I know this only affects In-App webviews + PayPal Subscriptions. We are using the HTML PayPal button to launch our subscription flow, and within the iframe that shows up, the very last step will never get loaded due to a mis-configured `X-Frame-Options` value, as you can see from the screenshots below. (Apologies as some screens contain non-English contents, I've added captions where necessary)

We managed to capture this error message for the very last step (where it says "Webpage not available"):

Refused to display 'https://www.sandbox.paypal.com/webapps/billing/subscriptions?ba_token=BA-6TU87090GM8..............' in a frame because it set 'X-Frame-Options' to 'sameorigin'.", source: about:blank (0)

Any updates about this? I have the same exact problem.

@sad-boi unfortunately no, still stuck on this...

Obviously I'm no PayPal engineer, but maybe this can be resolved by removing the `X-FRAME-OPTIONS: SAMEORIGIN` response header at the very last page?

```

Or am I missing something entirely?
