You should click on Edit the main product, then in Product Data section, uncheck/ unselect the box in Sync quantity option: Sync the quantity of the main product with associated products.
This will allow customers to buy added products with a different quantity from the main one.
Please check your product setting again and adjust it, you're good to go.
It was working recently, but now when I increase the 'added' product, the 'main' product also increases.
In 'Cart & Checkout' settings, 'Change quantity' is set to 'Yes'
In the 'main product', 'Custom quantity - Allow the customer can change the quantity of each product' is enabled.

That is precisely the problem.
I've done that.
I even tried disabling all plugins, still doesn't work.
Screenshots attached
v2.0.7, WP 5.4, PHP 7.3, WC 4.0.1
Okay, I've worked out that is has something to do with my theme.
The theme is making changes to the +/- buttons.
Solved: Have disabled the theme's modifications to the +/- buttons
