Fastify: SEO Onpage

ATTENTION TO BUSINESS
DO NOT INSTALL THIS APP UNTIL YOU GET A LIVE PERSON.
They never respond.
The Apps do not do what they said here.
We paid the one time $25 with no refund guarantee for a better Business Experience and nothing happened, sound like scam.
Their app make trouble with products links into Google as
URL not found (404).

We're tried to reach the support with no response to our issues. A fourth request was submitted. We have problems with the app, and there is no welcome email.
At the moment still can't have email support, Inconvenient and unprocessed needs. We deleted and removed all code as well.

Solution:
For the best Business environment, the APP needs to be removed from the Shopify app store until further notice.

Thank you
