I don’t know why i’m unable to download it on my app

Hello, I followed the article " Data Collection on KoboCollect App" but I still have the problem.
I checked my questionnaire on ODK - XLSForm Online. And it’s works on the internet. So I don’t know why i’m unable to download it on my app.
Please find attached the message I get from the app.
I’ve been using Kobo for a long time and it’s the first time i get this problem.
Thank you
