Eidon review for Mailchimp Email SMS Marketing

There's only one day left before the MailChimp/Shopify integration ends and there's a huge notice when installing this app: "Important! Please archive any Mailchimp welcome e-mail automation before installing ShopSync If you have welcome e-mail automations running in Mailchimp, please archive (not pause) before installing ShopSync. There have been reports that emails have been resent after performing sync, and we are actively investigating the issue. Other automations are not impacted and can be migrated as noted in Mailchimp's knowledge base article." Seriously, who is stupid enough to move forward after reading this? And reading how ShopSync is replying to other people, seems like a huge loophole where ShopSync & MailChimp will not take ownership of any issues, truly try to help their users, but instead play the "blame game" and refer to the other party over and over. Removing this app right away...
