Canon R6 MK 3 Holy Grail

Connected via USB and can manually change camera settings; however, unable to see JPG after shot. So, Holy Grail is not working on this model.
Conceivably, could it be a bug in QDSLRDashboard? Canon only has S1 and S2 JPG sizes on this camera? There is no S3 JPG.
Is this a case of Canon tightening access? Anyone know of plans to address this issue?

R6 Mark III – qDslrDashboard Wi-Fi / Live View / Capture Sample issue
Camera: Canon EOS R6 Mark III
Firmware: 1.1.0 (latest)
Phone: OnePlus 12
OS: ColorOS 16.0.10
Android: 16
qDslrDashboard: 3.6.16
Connection procedure:
On the R6 Mark III, I use:
Network → Advanced connection → Connect to smartphone (tablet) → Add a device to connect to
The OnePlus 12 then connects directly to the camera's Wi-Fi network. After the phone is connected to the camera via Wi-Fi, I launch qDslrDashboard and connect to the camera.
Problems:
1. After qDslrDashboard connects to the R6 Mark III, the app sometimes crashes immediately. If I reconnect after the crash, it can connect successfully. However, after a successful connection, pressing “Capture sample” triggers the camera to take a photo, but the captured image is not transferred back to qDslrDashboard.
2. Live View is also unavailable/disappears after connecting the R6 Mark III to qDslrDashboard.
For comparison, I use the same phone and qDslrDashboard setup with my Canon EOS R5, and the connection, Capture Sample image transfer, and Live View all work normally.
Therefore, this appears to be an R6 Mark III compatibility issue with qDslrDashboard, rather than a Wi-Fi connection problem.
Could you please check whether qDslrDashboard 3.6.16 currently supports the R6 Mark III, particularly for image download after capture and Live View?
Thank you.
