I am currently working with the toolbox (latest version) and after resampling the Sentinel 2A tiles to one resolution I wanted to make a mosaic of four tiles (Marocco), but despite all tiles looking great after resampling (10m resolution), all except one get a coarse resolution in the final mosaic, so there is a seamline (picture attached). I have the same problem when trying the mosaicing in SAGA or ArcGIS or via the sen2mosaic batch processing. Working with the 1C tiles in SAGA and mosaicking these is no problem, so I guess this is something regarding the 2A tiles that I do not understand. I am fairly new to working with SNAP, so any help is appreciated. I feel like this is a very basic problem due to something I have not considered.
Thank you and kind regards.
