Hi!
Inspecting the L2A uploads to GEE, I found that the Blue band was overwritten with the Red Edge 3 band -- I think there may be a typo in line 265 of S2L1CTOL2AGEEbatch.py3. As I understand it, f20m should read f10m.
Thankfully the TCI_B band can be used in place of the Blue band, since the values are the same.
