Hi,
Following up from this thread: Misalignment between Bands in Mavic 3M multispectral images
I also have a M3M dataset that is showing this misalignment, perhaps not quite as bad as the original but it is still showing up.
The topic is now closed, so I am not sure if there was any update to this? Is everyone else with a M3M still seeing this issue?

We have not resolved this yet, no.
Thank you, is there anything needed in terms of datasets to help with this? Is the issue being tracked as I couldn’t find an open issue for it on GitHub?

### How can we reproduce this? (What steps trigger the problem? What parameters are you using for processing? Include screenshots. If you are having issues processing a dataset, you must include a copy of your dataset uploaded on Dropbox, Google Drive or https://dronedb.app)
Parameters: dsm: true, radiometric-calibration: camera+sun
