Google Maps doesn't work on search results pages

I updated DT to 8.9.7 and Google Maps is OK on listing pages but:
1: Google Maps doesn’t work on search results pages . Settings are the same and seems to be OK:
Show Map Open = ON, Position: Top of page, Color = Default , Map Clusters Markers = OFF
2: With the Old Home Page Editor/Content Element/Google Map Bar doesn’t works too.: A grey screen replace the map !
Its the same on the test site: (WP 4.9.7 , DT 8.9.7) or on the main site: (WP 4.3.17 , DT 8.9.7)
Is it an already known problem ? Is DT9 fixed it ??
Thanks for your Help
