Typeform Extension not working

[Konst]

Hi Team

We have been using the free version of your great product for a long time but after the plan policy update we lost our functionality due to the inability to use the extension.
Please explain me if I have a board that is shared between many users, will the my own extension be available to them if only I purchase a subscription for my account? Or every user should have to purchase a subscription to have this extension? If it's just me - then what are the limitations?

Thanks
