well, the temperature of the liquid in which #the tea steeps affects the strength/flavour of the brew: https://teafloor.com/blog/how-water-quality-and-temperature-affects-the-taste-of-tea/
So if you add milk first, you do lower the temperature of the water and thus the flavour. :)

Of course all that is meaningless if your way makes your cuppa the way you like it!

I'm not gonna stand in the way of a fellow tea drinker, or #theeLeut as we like to say in Dutch. ;)

Enjoy your brew!
