What’s up guys, I’m currently onboarding a client but everyone they try to add their credit card as a payment method it says "Payment authorisation failed." as well as "This action couldn’t be completed. Try again with a different payment method." along with the error code OR_BACR2_31 They don’t want to use another payment method. The account we were using was new and we had to create a new payment profile. Does anybody experience the same thing?

I am running google ads for a software development & plumbing company. My question to all of you experts out there— how do you analyze if your landing page is the problem. This is a complicated question because of the amount of factors that can skew CR%. Sending irrelevant traffic to the greatest page of all time means low cr%. What steps do you take to accurately assess that your LP is the problem? P.S. — My CR% for both of my clients is ~10% for phrase & exact match keywords.
