Have a feeling this is about the revised PHB, with WotC trying to figure out if there are spells they can remove and/or replace, with perhaps some of them becoming a part of monster/npc stat blocks.
The Conjure line of spells were left out (although you can add them back in as some of your optional 5 spells) and I wonder if that signifies something about how they plane on handling summoning in 5.5e PHB, in other words replacing the Conjure Spells with the Summoning Spells in Tasha's and Fizban's?
If you say yes it lets you write-in up to 5 spells.I thoughtfully answered the first few pages of spells, diligently looking up any spells I was rusty on, then realized I just didn't want to do this anymore.
So I just clicked "next" a lot without rating anything, to see what was coming up. It asked me to rate twenty pages' worth of spells! And then it asked "Would you like to rate any more spells?" to which the answer was clearly NO. Who knows how much longer the survey would have lasted if I'd clicked "Yes."
