We recently switched from PayPal to AffiniPay and were blindsided when all of our existing PayPal subscriptions were automatically cancelled. According to the Wild Apricot help documentation, "If you have recurring payments set up, you'll need to stop those payments through your existing payment processor".

We expected that our members' PayPal subscriptions would continue and we would have to deal with them manually until they switched over. We were not equipped to handle a mass cancelation of subscriptions and now expect to lose members as a result.
