Hello Diegpl
I already shared with you the import process and how you can get those leads from CSV files using the import option. Hope that helps you. Kindly follow the steps,

And another issue is you are getting errors, you have to follow a few steps to clarify, that is
1. You must have PHP 7.4 or later to use all the features of Propovoice.
2. Your browser must not block JavaScript, as we use JavaScript heavily for our plugin features.
3. The AdBlock extensions in your browser should not block Propovoice scripts.
4. The security plugin on your WordPress install or Antivirus on your computer should not block Propovoice scripts.
If problem is there, kindly Check your theme and plugin conflict:
1. Please deactivate all of your plugins and see if the issue is solved. If yes, then there is a plugin conflict. You can activate half of the plugins to see if those were causing the conflict. If yes, then reduce half from that and see how it goes. In this way, you can check for conflict faster. If it feels complicated, you can activate each plugin one by one and find out which one is conflicting.
2. If you see that the issue is still there after deactivating all the plugins, then you can switch your theme to a default WordPress theme like Twenty Twenty Three or Astra to ensure that none of the theme customizations or scripts are conflicting.
