Problem with 10m resolution?

dear marpet, sorry to trouble you again, I have successfully completed atmospheric correction of Sentinel- 2A level 1C and covered the TOA to BOA, but I ever saw the topic in the step forum which said that there was problem in L2A product of 10m resolution,it is real? if yes ,what is the problem, how to solve it ? or if I can directly use the result of L2A product to calculate the index or do others?

I don’t really no Sen2cor and can’t help you.
But I started at the right place an appropriate new thread for you.
