We are sorry for the inconvience. However, we haven’t encountered this issue on our end.
We have surveyed other tickets and solutions, Even In other Questions raised on WordPress Community, a similar issue was not caused by the Plus Addons itself but rather by the custom code added to the page. Activating the Plus Addons seemed to overwrite that code and enabled the scroll. We recommend checking if there is any custom code present on your site that might be causing the problem.
If custom code is not the cause of the issue, You may try disabling other 3rd paty plugins as well and keep TPAE enabled, That way you will be able to find a conflicting plugin.
Or You may try to make one blank page with Just one elementor widget and try, If that is also having this same issue?
Above observations from your end will help us find something, which might be conflicting.
We appreciate your understanding and look forward to solve the issue on your site.
Best Regards.
