Problems with uploading encrypted forms with ODK Collect to ONA

I have designed a form with XLSForm, and generated a private and public keys and uploaded the form to ONA. I am able to complete the form using ODK Collect, but unable to upload the form into ONA.

I am using ODK Collect 1.20.0 with Android phones (Samsung J7 or LG K9). I am using ONA as my Aggregate instance.

I have followed all the steps highlighted in ONA documentation for using encrypted forms.

I do not have sufficient rights as new user to attach test forms or provide links.

This is likely an Ona issue. Ask for help at
