Hello, I just created a free account to make one survey, and it needed to be answered in the window of 2 or 3 days, because it was an urgent matter.
When people started to complain that the form was closed, I spent a lot of time trying to understand why it was closed if the settings were saying it was open. THEN I entered my workspace and saw the small message telling me to upgrade.
It costed me a lot of time, and it wasn't warned beforehand (or at least not clearly). It was very frustrating for me and completely put me off the possibility of subscribing to a paid plan. I really think you should reevaluate this strategy, because it is very annoying and makes the service look like bait. For my part, you have lost a potential customer.
