I found the solution, in case anyone facing the same problem, hope below solution that works for me able to help you too.

It was this google map method “map.fitBounds();” that overrides the zoom option.
Got the clue from this post https://stackoverflow.com/questions/33839714/zoom-option-is-not-working-for-google-map

The said method has to be removed, just look into the PHP file of where the Google map embed code place:
/ere-template/single-property/google-map-directions.php

Search for this line of code “map.fitBounds”, removed it or comment it out.

Lastly, you need to replace it with another code method in order for the map to works correctly, else the map will stop working after you remove above code, replace it with below:

map.setCenter(bounds.getCenter());
map.setZoom(16)

Just change the zoom level to the level you prefer. That’s it! Hope it helps!
Feel free to reply if you found a better solution.

Haha, no 4 is funny…
I just afraid the wp upgrade will effect others plugin functionality.

Thanks for the solution! i will try it out!
And appreciate the development of such great plugin – Transposh !
