Unable to activate pro version – Code Bangers Time Clock

I recently purchased the pro version of your time clock plugin and have been having problems getting it to properly activate. I’m not entirely sure what the activation does however, I’m never a fan of error messages in my admin center.

Issues Encountered

1. The first error message I received made me realize your plugin is dependent on WooCommerce being installed. After installing WooCommerce, that error message was resolved.
2. I went back to the “All In One Time Clock Activation” page /wp-admin/options-general.php?page=wc_am_client_aio_time_clock_dashboard and attempted to activate a second time and received a new message. The Product ID I had entered was reduced to 4 characters after submitting though so I quickly determined I probably had copied the wrong values from the “API Keys” page found on: https://codebangers.com/my-account/api-keys/
3. After providing the correct values it successfully removed the error message alerting me that I had not activated yet however, it still showed the “API Key Status” as being Deactivated and I did not see an activation appear in the “API Keys” section of My Account

Everything seems to be working now but, concerns over the error messages.
