I get this error when trying to complete a purchase from an online merchant.  I've successfully completed purchases in the past (latest was 2 months ago) but now I constantly get this error.  I did not do anything different.  Any help will be much appreciated.  Thank you

Hello @LeighK1, 

Welcome! Thanks for visiting PayPal's Community Forum. I'm sorry to hear about the error you've run into trying to use PayPal recently. Normally, a 400 error code is normally related to an issue with with your internet. Are you currently travelling by chance? If not, you may want to try first clearing your browser's cache, cookies, and browsing history. If the issue persists, you may want to reach out to your internet provider to troubleshoot the issue further. 

If all your settings are properly set with your internet provider, the issue may be then be with the merchant's website. My apologies for any inconvenience this may present. 

Best wishes!

Hello! We have an OpenCart store and have modified the SameSite=None code, but the same error message appears, causing customers to fail checkout multiple times. Do you think there might be something wrong with this? The code I modified: https://forum.opencart.com/viewtopic.php?p=870593#p870593
