I added a 360 to an existing Google Maps location and Google Maps used the description field as the image title.
IE when I view the image in Street View, the small badge on the top left of the photo reads...
- [Profile photo, profile name]
- [Street View - Jun 2019]
Also, I edited the field to something more appropriate and resubmitted the image. Google is still displaying the original description. Is this usually resolved within a few days?
