To download Sentinel 2 raw band images, we suggest choosing another method (custom scripts) to delete pixels without data. It is not right to convert the raw image band into two bands!
This makes it difficult for those who have designed and manufactured their algorithms on a single raw band basis.
Please solve this problem or leave the download of this feature as the user chooses
Agreed, we are already working on a better solution and should have this fixed within a week.
I am happy to inform you that with the latest update of the app to v3.0.51 we added an option to let you decide weather you want to include the dataMask band into your raw bands for download or not (default is not include).
