Value Orders vs. Quantity Orders

I’ll preface this topic, by saying that I’m a convert to value orders!

Tonight, I was having a play around in the app, in preparation for pies and came across behaviour that I wanted to query.

As an example, Barclays, which is fractional. If I wish to place a value order, I am informed that the minimum purchase amount is £1. However, if I switch to a quantity order, I am able to purchase the minimum listed quantity; 0.1 shares, or roughly 12p.

Obviously, this is a tiny amount, but it allows me to complete this in virtual mode. Is this expected behaviour, @George?
