That's what I did, but it still says that the band sizes are different
Additionally, what I exaclty would need is to mosaic the granules 1 and 2 (see right side of the image attached), since it covers my study area. Problem is that one is in zone 36 south and the other one in zone 37 south. If I open both in the same zone (either 36 or 37) I end up losing part of my study area.
Anyways, whether I open both in the same or different zones I get the "Product 'sourceProduct2' contains bands of different sizes. Currently it is not possible to use it for mosaicking"
What to do what to do...
