Thanks a lot for being an early user. It means a lot that you trust us with your development, and that you're helping with suggestions.

It looks like this [support topic](https://wordpress.org/support/topic/field-type-textarea-not-show-in-admin/) has a similar issue: >Yes, if add too much text in textarea field type it isn’t rendering in block editor
