"Thanks for reaching out! We are aware of these updates from Shopify. They will not affect OneClickUpsell in anyway. We work closely with Shopify and are operating with their approval."

Recharge support:

"Rob here with Recharge Customer Support.  Thanks for reaching out!

You're right we are getting a fair amount of questions about this and understandably so!!  However, not to worry.  This does not apply to ReCharge.  We have previously been authorized by Shopify to bypass the Shopify checkout so the ban they're referring to does not apply to us as an authorized partner.

If there is anything else we can help you with, please let us know."
