Shopify Makes A “Mistake” On Transaction Fee Returns

This is strange on so many levels…
To categorize a serious financial change as a “mistake” and try to play it off as no big deal is not a good look for Shopify.
Edit: Stripe stopped refunding their fees in 2017.
This may be a “mistake” in the sense that their accountants didn’t realize that they were refunding fees to merchants and then not getting those fees refunded by Stripe (who Shopify uses for payment processing).
Strange.
