Thank you Eli, I confirm this is the same for me (iPhone, Wifi)
Tested here and same result (an aerial image of my current location appeared briefly before being replaced by the image shown above).
Thanks folks for the report. We have escalated this issue for further investigation. We will share an update as soon as we can.
Best,

Has anyone experienced the issue on an Android device?
Yes. I am using an Android phone.
Thank you for the confirmation
It seems to be working for me now.
