Have to clean/rebuild project every time

Hi,

I've just started to use Xamarin Forms and every time I want to run an iOS application in the simulator I have to clean/rebuild the solution. If I don't then it appears to still compile, but always runs the previously cleaned/built version... Am I missing something? From Googling it seems I'm the only one with this issue! Tried 2 separate PCs and a fresh install of everything. Also tried going back a few versions of Xamarin Forms but no luck

It's incredibly annoying and rendering it almost unusable.

Thanks!

VS 2019 16.1.6
Xamarin Forms 4.1.0.581479
