@samtulana – Can you clarify or elaborate on the follwing
After updating WordPress, all the columns and other functions simply went astray.
We are working on using it by default, and you already can, but there have been no issues using it thus far except we don’t have our shortcodes all converted to blocks. Otherwise you can enable the editor in Popup Maker settings and use it just fine now.
Also any changes you see after a WP core update to your editor content would likely not have anything to do with Popup Maker. Explicitly for the reason that the editor is a self contained part of WordPress, what it outputs is not modified or filtered in any way by our plugin. So it’s very well likely that due to the new column changes in WP 5.3 your simply seeing issues related to those changes.
Hope that helps. If your issue is resolved please take a moment to rate and review the plugin or support.
