Hello @sylb ,
If you're trying to switch back to Klaviyo's free plan but keep getting an error, try using an incognito window or clearing your browser cache. Sometimes, an outstanding balance on your previous paid plan can prevent downgrading, so check your billing status under Account > Billing. If the system is stuck, try refreshing the page, logging out and back in, or switching to a different browser or device. Since you no longer have access to live chat or email support, you can reach out through the Klaviyo Community or their Twitter/X (@klaviyo) for assistance. If the issue persists, waiting a few hours and trying again may help, as account changes sometimes take time to process. Let me know if you need further help!
