@BritoAlv just a follow-up question on this: on the devices that weren’t able to scan the QR code, can you scan them successfully using Android’s standard QR code scanner (https://www.android.com/articles/how-do-you-scan-qr-codes-on-android/)? That won’t set up the project in Collect, but it’d be interesting to know if that scanner can detect and read the data.
