Stop forcing banners and promotions on users inside Proton Mail. It Is highly distractive and disrespectful.
Commercial interests are communicated via a one-time email, but mustn't be forced onto the user by invading their apps. I'm a paying member, big plan, yet I'm being - frankly - spammed by these 'offers' many of which don't apply to me anyway. The important point: Stay out of my area. It's not yours to enter. I pay for it, I work here, don't distract me. It also makes me wonder, how great your dedication to privacy really is, since it is like putting a salesman right into your kitchen telling you constantly to buy new stuff. That really puts me off.
