No update. No backup. – Contacts Backup - IS Contacts Kit Free Review

Dear Contacts Kit, your app keeps reminding me to backup my contacts, but I can’t because you haven’t updated your app for iOS 11. Frustrating. It was a great app until then. I know it was free for me, but on the other hand, it’s useless now. Please update. Thanks.
