Newsletter Builder and 3.69

Hi Dave

Are there any known issues with newsletter builder and 3.69?

The plugin generates the following url to unsubscribe to newsletters (placeholder: #unsubscribe_url#)

https://domainhidden.co.uk/newsletter-manage.php?n=895&a=531941d980b1&m=5&u=1

This link opens the page but unchecking the newsletter and saving doesn't result in any change.

If you remove &u=1 from the url the form works, but removing &u=1 also removes the error and alert instruction: Uncheck any newsletters you don't want to receive OR uncheck all lists to unsubscribe completely.
