Survey questions don't pop up in mobile app (Field Survey Application)

I'm using this app https://marketplace.creatio.com/app/field-surveys-creatio

I've created a questionnaire https://prnt.sc/sffjnq and I've added this step to Field visit rule https://prnt.sc/sffkeq

On mobile app I see this extra step, new records appear in section Surveys, but in mobile app (iOS) screens with questions don't pop up like on this screenshot https://prnt.sc/sfflkh 

Any suggestions?
