Look like in 2.x verison they changed something related to add-ons...Previously we could installa add-ons directly in the WPForms menu with this nulled version but NOW... they install but NOT latest version.
I tested this in 2 WP installation:
WPForms MailerLite 1.3.0 its the installed version BUT latest looks like is 1.4.0 and if u try to update it say "you already have latest version" and it stay 1.3.0.
Please check if something need to be fixed in the nulling process.
Thank you @Mrsam_1
Also i tried to disable and re-enter key now it doesnt work:
