Hi Humayon,
I have purchased and updated the WPDM Form Lock plugin. I also made sure the other related plugins like WP Download Manager, WPForms, WPForms Zapier, WPForms Form Abandonment, WPForms Mailchimp, WPDM – Gutenberg Blocks are also updated to the latest versions.
The issue is still not resolved.
Please investigate the issue and let me know how we can fix this.
Thanks
