Tipo Appointment Booking

Once installed, the app stopped all products from being loaded into my cart. So, people were able to take a course (yay!) but any ebook, business plan or other product was not able to be purchased. I lost sales. Took 2 hours with shopify team and they couldn't figure it out. Finally uninstalled the app and sure enough, my site was fixed! Sounds like they have quite a bug to workout.
