Hello @madiluu ,
We are extremely sorry that you have this bad experience with our plugin. But the issue you had with the layout of your website could be happened due to any third party plugin conflict or your used theme. So, it would be very helpful for us if you could share the system info of your website from Elementor > System Info. Otherwise you can share the live website URL where you have faced this issue for further inspection.
In our development environment we couldn’t reproduce the deprecated warning as well. It would be very helpful for us if you could share any screenshot about the warning to understand it clearly.
However, we have checked both on forum support thread and in our support center but didn’t find any support ticket regarding this matter. So, we recommend you to open a support ticket at our support center with the above information we asked. We will try to find out the actual issue and let you know the update ASAP!
Waiting for your valuable response and we are always here to help you.
Regards,
Benjir
