Google maps theme

I have implemented Google maps in my Android application and everything looked clean until few days. Previously the maps looked like the below image

Now the map has a new look similar to image below

I have not changed or updated anything in the implemention, yet there are dark lines on the map which makes it difficult to read the places.

Any help is appreciated. Thanks

Note: I have downloaded the images from Google for reference, please ignore the xml layout changes.
