Reusable Blocks Disappeared from Website

I had reusable blocks on my blog for people to sign up for free resources and all worked fine just late last week only to get back on today to find that

A) Yoast SEO of disabled and I had to reinstall plugin (fixed now)
B) All reusable blocks are gone from my blog posts. They show up on inside block editor looking different than before but nothing shows up on the blog post itself.

Did I miss any announcement about that in regards to latest update?

Please advise. TIA
