Changes in Usage limit for free version in Zoho creator?

Hey,

We have an application for internal process, which we have been using for the last one month. We had 6 active users, but all of a sudden today, all except 2 users got deactivated. When we tried to activate the users, there was a pop-up notifying to upgrade a paid version. Not sure if something has changed in the usage limits for the free version.

Has anyone else faced the same?

Thanks
Vikas
