thanks a lot for helping. I have tried to use rasterio 1.2.0 but
unfortunately I am experiencing the same problem
Do you know if there is anything which can be done to avoid this
issue? Otherwise I will need to change my code and maybe use GDAL
virtual rasters to do the merge process
thanks in advance!
