Thank you for your feedback.
Please note that LayerSlider does have an automatic update function and it is working properly.
However there are some unfortunate cases where the update method is being interfered by a 3rd party theme or plugin.
If you receive an 'Update package not available' or similar error message during the update process, it might be a symptom of this as well.
We are constantly notifying and working together with various authors whenever we notice such issue. Unfortunately, these issues cannot be fixed from our end, a temporary solution is to update manually or temporarily disable other plugins and switch to the default WP theme.
In case you need help with the updating process, you can find detailed update instructions in the Documentation .
Furthermore, if you need additional assistance with the plugin or its features, please contact our support team on the following URL, as we can only provide support there currently: https://kreatura.ticksy.com
Looking forward hearing from you.
If this solution would change your mind about the plugin, please consider to raise your rating - that would mean a lot to us.
