See the screenshots. As soon as I navigate to basically any page in Hubspot, I am offered a paid subscription. The modal window basically blocks all navigation, so the option offered (buy or Contact sales) do not even work. Obviously I am using the Free version but I should be eligible for that. I was able to contact sales by navigating back using the back button of the browser, but they just said that this is something which should not occur.

Hi there @LordFalck,
Our team has deployed a fix on our end. Can you confirm if you are still seeing the issue on your end?

I would say the problem disappeared pretty much the next day after I had reported it. Anyway, problem solved.
This was resolved already. Incognito windows did not help and it affected many users, but it seems some lvl of patch was done to this some week ago already.
