Interesting. I have now used the Choice app on my phone (android) to make a res in Stockholm, and it works fine if I select "Everyday Rate".
But when I switch to "Reward Points", every hotel shows "no availability for that rate" on many different dates.
Strange that you and Ised have been able to book with points without having to accept the disclaimer that shows up on the Choice website for me.
Glad you can, as it is a great use of points. But I'm not going to make a non-cancellable res until I'm actually in Stockholm.
