we are loosing pur organic traffic due to poor Core Web Vitals, ale very slow loading time ofour website. Out IT department says its due to Slider Revolution and using unison (old and not google supported) framework. How can we fix this issue, when no optimalisation tactics work. Should we change our website to redux?
First of all, you can try to migrate away from the Unyson page builder you can migrate to the Redux framework plugin. Migration is available under Jevelin (admin sidebar) > Framework Upgrade.
