What is the problem?
I have some strange problem with v. 1.23.1
If I use constraint for numbers input (e.g. ".>=18 and .<110") this constraint works even if I enter a valid value (e.g. "30") and I see restrict message.
But if return to the previous question, and then came back to number input - everything works well.
The similar problem with constraint in multi_choice questions. E.g. if I use for constraint construction like "not(selected(., 'do_not_know') and (count-selected(.)>1))". Some times its work correctly, sometimes not.
In case this works incorrect - a trick with returning to previous questions work too.
