Huel RTD fishy aftertaste?

Great to see Huel innovating!
I thought i’d post separately. I’ve been drinking enough of it to notice There is a chalky aftertaste despite me shaking up the drink a lot. It’s not the batch, it’s just how it is. That I can live with. What I did notice after drinking (and I have verified not drinking the RTD)

What I noticed after is a very ‘fishy’ breath smell after drinking the RTD that I had wonderful comments on.

Has anyone else got this from people close and dear to them?
