Pin Map with grey background instead of the map


I've been created a pin map and all the pins are there correcty. But the background map is not been showed, only been shown a grey background.

Please take a look in the image below.

Has anyone faced something like that ?

Version 0.45.3

Thanks in advance for helping me
