Attacking the portal does not neutralize it. Experience shows that the attack will pass after 4 hours
The same phenomenon occurred
I attacked but it doesn't turn white
The same thing still happens.
I will report that there was a workaround.
When I use "battle becon" for portal,
the attack now goes through
Thanks for sharing, @nekoiscat! Would you mind sharing a screen recording of this? We'll take a closer look.
Noticed the same also last December, but do not remember seeing this again since last December:
Report of the issue with videos from last year
This has happend too me before and now it happend again with 7 portals being invunerable.
Sorry for the delay Agents! To investigate and help you better, please share the names and the locations of the Portals that have this issue. I'll share it with the team to look into it. Thanks!
Putting any type of beacon on the portal will neutralize it
Letting them decay also works.
I've had this problem multiple times. Leaving it alone for 30 minutes to 6 hours resolved such issues in the past. It's like the portal is in a "locked" state. I just attribute it to server lag.
Not invulnerable portals, but persistent links, on scanner after restarting it, and on Intel.
Will see if they disappear.
Just to add on, here is another thread about this issue, which also has a video posted.
