Sync issues still not addressed months later

Sync problems. Mailchimp support directed me to uninstall every other plugin on the site to get theirs to work. Not realistic. And to uninstall and reinstall. Which didn’t solve the sync issues (sync not working, endless syncing without actually syncing as others have reported). I started trying to address the problems months ago. With their resources it’s pretty amazing that they don’t have this fixed yet.
