Now this seems an improvement for sure, also I am now able to manually resend requests from Stripe to WP, which had previously failed.
I also notice that it looks like as if the same webhook were set up multiple times (which I did certainly not do manually) – I am having
https://(domain)/?asp_hook=live
five times in the list of webhooks in the Stripe dashboard, with four of these actually tracking activity. Does that make sense?
