Thanks for the reply!
I understand the intent of the touch device.
I found the cause somewhat and will describe it.
When operating with a touch device such as a smartphone, it is not possible to use a finger on a marker icon.
The finger operation does not seem to respond on the marker icons.
This DEMO is easy to understand.

I am having trouble with the same thing happening on my site.
I know it’s strange to ask here since it’s a third party plugin.
I’m stumped.
Do you know the cause?
My finger does not respond on the marker icon.
