Yes, I updated the form after giving them access.
I now have two other issues - I have three languages: English, Arabic, and French. I have set up the app users and sent the QR code to them, which I created after the most recent update. However, only the English and French versions are showing. The Arabic, most recently added translations, are not showing in the collect version.
The second issue is that while I am seeing the submissions come in - the data, aside from KEY SubmitterID SubmitterName AttachmentsPresent AttachmentsExpected Status ReviewState DeviceID Edits FormVersion is totally empty.
