This is an odd problem we're having. Whenever there is a notification turned on (both after a form is submitted or after a Stripe payment is processed), the form stalls out at that point. For example, if we have logic set to send a notification email when a form is completed, when the user presses submit, the page continuously loads until there is an error message saying the browser can't connect to the site anymore. The emails in the backend that are supposed to receive notification never do, as far as I can tell.
This is an even bigger problem when we are trying to collect payments. If we want notifications after a payment, the purchaser enters their information, clicks submit, but they stall out again. The payment seems to process in the back end and the purchaser is charged, but they would be unaware of this since the page stalls out before reaching the confirmation language.
Has anyone else run into this problem?
