I'm fond of the product and it's been a part of my subscription for over a year now. However, I've noticed that each new box arrives with the powder increasingly more caked. The last one came in a single solid block and required quite some effort to break apart. After checking the bottoms of some older boxes I realized they are all of the same batch: 211616. So, my question would be: is new Flow still being produced and should there be any deliberations about consuming the caked version of it?
