Thanks for letting us know @mrpatg. Version 2 introduced multi rows, so any previous version will not have the multi-row addition.
The changes should have been backwards compatible, and should only have affected users who added an additional Section with the “new-row” CSS class, unless you were already using a bespoke CSS class that you had called “new-row” prior to the plugin upgrade?
Would you be able to double check that it isn’t a caching issue by force-refreshing your page (CTRL+F5 on a PC, CMD+R on a Mac), clearing your browser cache (or testing your changes in a different browser), and refreshing/clearing the cache on any caching plugins that you may have installed on your website, or have as part of your hosting?
If you’re still seeing the issue, would you possibly be able to send us a link to your form so that we can take a quick look and try to resolve the issue for you?
Many thanks.
