HI, I tried 3 times today to make a purchase each time selecting Paypal as the payment method. At the end of the authorization process it said that I was authorizing Celery to make charges on my Paypal account: Do you agree to this? Select Agree or Cancel. Every time I hit agree and it responded by saying it was returning me to Celery, not to Particle.io Personally, I think that’s where the glitch is: The Celery setup process hijacks the buying process (as it did in all three cases here), and the person is never redirected back to the actual purchase page to fully complete the purchase. This is why I never got a receipt and why Paypal has no record of me making the purchase. When I make a purchase on other sites, I’m always redirected back to the site to finalize the purchase details and then confirm it. I never made it back to Particle.io
Subsequently, I was able to make a separate purchase from your site using credit card. I immediately got a receipt. Again, I think the problem is that Celery is actually bad for your health.
I hope this helps.
