PayPal Buttons (Standard) - Error 400 on PayPal's End

Hi! Anybody else getting “Things don’t appear to be working at the moment. Please try again later.” when trying to start or modify a subscription using PayPal’s integration?


Console has error 400 for

Sometimes the error won’t happen on the first PayPal’s screen, but when that’s the case, it will always happen on the second, after clicking on subscribe (to select the payment method etc):

I contacted PayPal’s support but nothing so far. I noticed the issue a few days ago but I thought it was related to some changes I did to my CSP. Then, for testing, I reverted my changes, still no success. It’s been a long time since I ever got a successful subscription via PayPal, so I believe something might be wrong with my integration or with s2Member… :thinking:
