1) Jetpack Forms play nice with Gutenberg and the Block Editor. They better inherit theme styling and global styles. They use Block Editor Buttons for Submit (instead of HTML input). They just look better in a modern block theme without much fussing. Please make Mailpoet Forms play nicer with the Block Editor in the same way Jetpack Forms does.
2) Please work with Jetpack Forms team on their Integration so the Radio, Checkbox, and Dropdown blocks can map to Mailpoet Lists the way it does in Mailpoet Forms.
Both of these fixes would unify the experience between the two products (and I understand now you're sister companies).
Thanks!
