tagDiv Composer 2.2 to 3.9

Hi Guys, I’m experiencing a few issues having recently upgraded from WordPress 5.2.3, Newspaper 8.7.3, and tagDiv Composer 2.2, to WordPress 6.1.1, Newspaper 12.3, and tagDiv Composer 3.9.

For any pages created with tagDiv Composer 2.2, I can edit ‘Row’ and ‘Column’ settings, but I can’t edit ‘Element’ settings because the options panel doesn’t load, it simply shows the ‘Welcome to tagDiv Composer’ screen with the ‘Add Element’ or ‘Load Template’ and ‘Website Manager’.

If I add a new row, and a new element, the settings panel has CSS issues – all of the control panel stylings seem to be broken, and even the ‘Save’, ‘View’, and ‘Close’ icons aren’t visible.

Do I need to recreate all the pages using 3.9?
Could it be because of the lack of [tdc_zone type=”tdc_content”][/tdc_zone] at the start and end of my page content?

Thanks
Matt

Also, and I’m not sure if this is related, but even though I’m using the latest version of WordPress I’m still seeing this issue in Jquery Migrate Helper.
