Hi Rui
Thank you very much for getting back to me, and thank you for sharing the article.
I have toggled “Enable only in Mobile devices” to: Off, and so far the mobile menu is now persistent, I am not having the issue anymore.
I have saved the link to the article in case of any issues in the future.
Thank you for the plugin by the way, much appreciated, it’s exactly what I needed.
Kind regards.
