Free-level was not update

Leaky Paywall does not update the expiration date of free-level users.

– On that site, we have set up to read 10 articles a month.
– When the user registers to the free-level, the expiration date is set one month after the registration date.
– The free-level user’s plan name (in the dashboard) is “non-recurring”.
– The expiration date of free level users will not be extended even after 1 month.

Why is this?
We want you to support.
