Recharge Subscriptions App

As soon as we set this up, we had customers sign up for subscriptions. HOWEVER, this app does not play nicely with others. We added a slider checkout and days later realized no one could buy a subscription box because Recharge needs to redirect to their own checkout page, not the Shopify checkout. OK, we fixed that problem. Then weeks later, we made a tweak within the Recharge app that changed checkout so that the first option was one time purchase not subscribe and save. Now, NO items could be added to cart. Trying to figure out what went wrong now and just had to vent about how irritating this app is.
