Hi, I want to report a bug in Toolset Types when used in the latest WP installation that is 5.9 & 5.9.1.
I am using toolset types 3.4.15 (the latest version)
When editing/adding content to WYSIWYG Editor field in Visual tab, and update/publish it, the content in that field is not changing from the previous state.
I notice this is happen in WordPress 5.9 & 5.9.1, when I downgrade the core to 5.8.3 it is working fine.
I wonder if this already added in the next version of Toolset Types or not?
What you describe sounds like the same issue. (I just tested it again on a clean site and got the same result, whereby it works when editing pages with the classic editor, but not when using the block editor.)
The developers are aware of the issue, and I'm hopeful they will be able to resolve the problem before the next round of plugin updates, which is due soon.
