Semihandmade review for Engees Abandoned Cart Recovery

This is a whole lot of "NOPE!". Install take seconds and seems easy enough to use. But every abandon cart i tried to convert to a draft, i got App error messages saying "Unable to fetch checkout from shopify" with a clickable link (where it supposed to go, no one knows) that doesnt work either, dead link. The contact support button takes you to some shady unknown Whatsapp url to a company that has no name.
