Slider not compatible with Elementor latest version?

Hi,

twice i had to restore my site files and Db as every time i update to the latest version of Elementor (3.6.5), the errors just pile up and the error becomes fatal.
It’s the first time this happens with an Elementor update…

I raised the issue in a Elementor group and got this reply:

According to the error, the slider of your theme is using a deprecated class of Elementor. You need to contact them. They need to make their theme compatible with the latest versions of Elementor

Another comment said:

Elementor recently updated their javascript and functions, so it needs to be updated to include same

Is that so? If that’s the case, can you please update it please. Many thanks.
