Yes, multiple times with no response ever!
We assume other people are having issues as well. The "Squarespace Failed Customer Payments" page has refereced that afterpay can't be used when people use in-app browsers. This is the issue.
Which is silly because what business these days are not using social media to bring in customers only for them to not use be able to checkout seamlessly. We loose around 20-30 sales because of this a day with our rocord being 52 in one day.
We also get around ten or so complaints a week from people who have their orders cancelled by Afterpay because they take the money and then never complete the order with Squarespace, hence we don't know this happens until the customer comes at us saying we canceled the order.
Because of all these issues we have to have multiple tacky Aterpay help buttons all over our site so we don't miss any sales.
Squarespace - Stripe are good but when you throw in Afterpay it's a nightmare.
