HivePress is an open-source project and it’s powered by the community, if you have any suggestions for improving it or any bug reports please feel free to post them on the forum https://hivepress.io/support/
I still can’t quite understand what’s the issue with the heading tags, please let me know if you have any details that may help to detect this issue and fix it (e.g. some result of a Google SEO tools check, or any details about why the structure is bad now).
The homepage content is empty by default, it’s not defined by HivePress. If you imported demo content, you can simply edit the homepage in WordPress/Pages section and add/remove any headings. It’s almost the same for posts, the post title is H1 (like it should be), the rest is defined by the post content you add.
It’s a pity that a misunderstanding like this results in the first 1-star review for this plugin, our team works 24/7 to improve it and I kindly ask you to report issues or suggest improvements first, whether it’s HivePress or any other open-source software. Thanks.
