Iirc, I had same issue earlier this season, Fulham home cup game, which will have been the only time this season that for a home game, SC holders would have needed to go through this.
It had reset permissions for me and the bairn since last seasons play off games (last time it would have been needed).
I remember talk at the time of Fulham game was that permissions had reset between seasons (??)
So it's conceivable that people trying to to it now, who haven't reset the permissions earlier in the season (cos they didn't need to) are having to now.
Maybe??
