Hi, @LEVY1 !
Thanks for your question, I’m happy to share more information with you.
First, I do recommend responding to the chargeback and sharing any additional information and evidence you have. You can find more information on how to do that in this help document.
In order to be eligible for the Shop sales channel, your store has to have a chargeback rate of less than 1% in the last six months. You can find all the details about our requirements here. It’s important to remember that even if you aren’t currently able to use the Shop sales channel, that doesn’t impact your store or account as a whole.
Lastly, I recommend checking out our help document about preventing chargebacks in the future!
Please let me know if you have any other questions.
