Investigating feedbacks

I recently added some paying plans on Beanvest and I am trying to get feedback to understand better my users needs.

For the moment the few users I have are not actively using the tool. I emailed them to get some feedback and I think some features are still missing for it to be really usable, even though I got very few answers.

I also tried some Google Ads : the positive thing is that there is traffic on the keywords, I managed to generate clicks and registers with a small budget. This tends to confirm the product does not meet MVP requirements yet, because those users created an account but did not really use it. I also need to improve the onboarding.
