Scanned QR code works properly but fails when I use the import method

When I scan a QR code that contains the project settings, it works however, when I try to import it into Kobocollect, it fails

Welcome back to the community, @morriz!

Could you explain your issue a bit? Did you mean you could not get the blank forms to your app? Correct me if I understood you incorrectly.

basically, when I generate a QR code with all the project details and setting, i am able to scan the QR code and it works very well. so no issue with scanning.
when I get that very QR image and copy it into an phone android phone and use the Import QR it fails

Why do you want to use import, please - esp. as scan works fine. See documentation Data Collection on KoboCollect App (Latest Version) — KoboToolbox documentation
