Issue in custom maps API settings

I applied the Google Maps API which was doing good. If I change any server settings from the traccar menu, the custom API changed from

https://mt0.google.com/vt/lyrs=m&hl=en&x={x}&y={y}&z={z}&s=Ga

to

https://mt0.google.com/vt/lyrs=m&hl=en&x={x}&y={y}&z={z}&s=Ga

automatically.
Probably it need a fix.
Still it is not a major issue, but still it need to be fixed

It's already fixed.

I have the same issue after 4.2 upgrade. Do I need to wait for 4.3 or is there something else I can do?

You can wait if you want, but it's not a blocking issue. The map should still work.
