The most likely cause of this issue is that your Squarespace subscription has expired.
This problem can arise when Automatic Subscription Renewal is disabled within your Squarespace settings.
To check your Automatic Subscription settings:
- Go to your Squarespace dashboard
- In the Home menu, click Settings
- Click Billing
- Under Subscriptions, select the subscription you wish to review
- Check if the Renew automatically toggle is switched off
If your subscription has expired, you can also renew it here.
You can find more detailed information on the Squarespace FAQ page.
Once you have confirmed your subscription is active, go to your Spreadconnect Dashboard and click Reconnect to reconnect your Spreadconnect account with your Squarespace store.
