Hi Andrew,
Thanks for reaching out to us. We are sorry for your inconvenience.
Version 2.0 is a massive change, we have updated the whole codebase in this series for better performance.
Please download the latest (v2.0.20) Swatches PRO version and use it with the latest Swatches Free version (v2.0.20).
Here are the steps you need to follow:
=> Deactivate both Free and Pro versions.
=> Update the free version to 2.0.20
=> Download the latest Pro version from here: https://getwooplugins.com/my-account/downloads/
=> Manually update the plugin. Here is a tutorial on manual updates: https://youtu.be/anzv8IsiP2o
=> Then activate both the free and pro versions.
=> You will get a notice in the admin area for the migration process. Wait for the migration process.
=> Reload the admin area and check if the notice disappears. If disappeared check your site again.
Thank You
