I have a problem with my account
info@provocaazione.ch
I have this message "Your subscription has expired. This database will be deactivated soon unless you take action. Go to our customer portal."
From 2014 I don't pay anything! Why i need to pay now?
Please use a meaningful title.
That does not add more meaning.
I have edited it for you.
Thanks a lot for the answer!
I was doing some tests and I activated 2 additional users (so 3 in total).
Now I have deleted the two additional users, but I still have the payment message.
How can I go back to the free version?
Adding users might not have triggered the change, as Ermin mentions you might have installed additional app. Even if you do uninstall them the database will no longer remain free.
