Hello James,
We have an explanation for your not selected panos.
Our developers performed an upgrade on our servers last Wednesday that had the unintended consequence of subtly breaking some functionality in the review process. This error has already been fixed, and we are reviewing again all the images that were affected, to make sure that they get assigned a correct status, both in 360Cities and in Google Earth.
We are really sorry for this error, and we will put checks in place to make sure that it will not happen again.
Regards,
Elena
