2. You can add custom fields to a booking just by creating them 
3. When you upgrade license this is not done automatically you need to manually upgrade license also but since you have opened a ticket with Starter license purchase code we can not very you license so we can not send it to you here.
   

   You can download Amelia from your profile in our store. 

   We are sending you a short instruction on how to update Amelia to the latest version.

   Go to Amelia Settings/Activation, and make sure that the "Delete Amelia content" slider is disabled. 

   Then, go to your Plugins section and deactivate the plugin. If you're using WordPress 5.8+, you'll be able to go to the Plugins section/Add New, and upload the file you previously downloaded.

   When you upload the file, WordPress will inform you that you're replacing the plugin with the new version, so just confirm that. After the plugin is installed, activate it, and make sure to purge all cache from your website.

   Hope this helps.
