I've been trying to book a flight and get either a hung session at "Saving passengers" (if I don't choose seats) or just the "We're sorry, something went wrong" error if I do choose seats. I've narrowed it down to the use of eVouchers (I have two due to a broken First seat that wouldn't recline at all on a previous flight). At first I thought it was because I was trying to stack the AARP and Chase discount since I've had issues before with that so gave up on AARP and tried directly, but after trying 3 browsers (clearing all cookies) and removing each discount (aarp, chase, evouchers) one by one I can get to the payment page with every combination so as long as I don't use my eVoucher. Is this a known issue using eVouchers? Any idea on workarounds, seems pretty crappy that the use of what was a service recovery voucher isn't usable. I will note that the eVoucher is in GBP, I am in the US and the site when I apply it does convert the GBP (700) to USD (922) so not sure if that is an issue

To add extra fun, I just got an email that "Your flight to London is waiting" with a book now button so figured why not give that a go...that brings me to a page with "Your payment is in progress. Please don't refresh the page or click the back button. " which just sits there with a progress bar going back and forth, mind you I've not given them any payment details since the website errored out before asking for that...
