How many sentinel 2 products?

I do not have an answer to your question, but I suggest you check the inventory,which will give you a clear answer if something is missing

Hi all, S3 Inventory has been turned on for all the Sentinel buckets available via the AWS Public Datasets program. This includes sentinel-s1-l1c, sentinel-s2-l1c, sentinel-s2-l2a. The S3 bucket that contains these inventory files is sentinel-inventory and is in the eu-central-1 region. These inventory files will provide, on a daily basis, the inventory of all files in the buckets along with their size and last updated time. More information on S3 Inventory files here.
