Gravity Forms MailChimp Add-On was updated to version 2.2, from version 2.1. Changelog:
- Updated automatic update so that it caches remote requests for 12 hours to limit requests to update API.
- Updated phone number when set to standard format “(###)### – ####” to send in required format of ###-###-####.
- Fixed issue with groups not being removed correctly when using the filter “gform_mailchimp_keep_existing_groups” to override default functionality and allow groups to be removed.
