So after beating my head against wall I tried building a fresh payment form to test and low and behold it worked. So kept playing and discovered the issue is that the form won't submit and payments won't complete if there are two "Collect Payment" actions active in the actions & notifications list. I have used Stripe with 2 'collect payment' actions for years without incident and sometime in the last few days that has stopped working for me. I have one action for one-time payment, one for recurring payment and they are set to conditionally activate based on a radio button field (for "one time" and "Monthly" payments).

Has there been an update to the back end of Formidable in some way over the last few days that I didn't notice? what could have caused this to break across multiple sites?
