[2022] [DLC 3] One-Eyed All-Father Ubisoft Connect challenge stuck at 93/100

I have done 15 viewpoints, there are none left on the map to do, but the Connect challenge shows 93%. I have not quite finished everything in the campaign. Does another one appear? Is this related to the time-limited challenges not updating?

Regarding pictures, close your eyes and (i) imagine the Svartalfheim map, picture some viewpoint icons coloured green then (ii) imagine the Connect stats with the various tasks, the one called "One-Eyed All-Father" does not have a completely blue bar and has "93/100" by it.
