lmfwc_get_license function doesn’t work?

Hi,

I have an custom script that was working well, but i see yesterday that a problem with the function lmfwc_get_license.
I pass the key (not encryted) to this function to check if license is not expired.
But now the function always return false (i tried with 2 different license keys).

So i tried this code:

$license = LicenseResourceRepository::instance()->findBy(
    array(
        'hash' => apply_filters('lmfwc_hash', $key)
    )
);

Doesn’t work better ??
And the strange thing is that the result of apply_filters('lmfwc_hash', $key) is always the same, even i put a different license for the $key variable…

Thanks for help!
