Today, I open the game, and found that a portal disappeared, which was occupied by me, and the key also disappeared
and I use iPhone 8, my ingress game version is 2.68.2
If the key is also gone, that likely means that the portal was reported as invalid and has been removed from the game, which would not be a bug. If you believe the portal did not meet the criteria for removal, create a thread in the appropriate category on the Wayfarer forums and request for it to be restored: https://community.wayfarer.nianticlabs.com/
Alternatively, a portal can be resubmitted with a new photo and name etc.
Thanks you guys, I will try
Hey there,@Corticosteroids. I would suggest you access our Wayfarer community forum and create a new discussion in the appropriate category with sufficient evidence so we can look into it.
