David, I am having issues with the new version of Post Kinds. Although I am able to publish posts, I am finding that the content is disappearing from the screen in the editor for some posts once published:

I am also finding that some links are being stripped from Response Properties when I publish. For example, I tried posting this issue from my site, but it kept removing the Github URL when I press ‘publish’.
Here are the error details provided by WordPress:
WordPress version 5.5.1
Current theme: Collect2016 (version 0.1)
Current plugin: Post Kinds (version 3.4.1)
PHP version 7.2.33
