And now the stars snippet shows 0 Reviews (when there is actually is some), and still no to the structured data. So it actually made it worse.

Did you QA the update?

Mike, I would like to chat with your customer services department. Please have them contact me. I'd like a refund - this plugin is extremely slow to load, doesn't work as advertised, and has been more trouble that it's worth. I will return to yotpo or reviews.io.

Thanks.

Ok great, please let me know of an ETA for this advertised feature to be included in the product I'm paying for. If it happens to be longer than a few days, I'd like to know so I can proceed with the switch.

Correct, but they are not visible in google's Structured Data Testing Tool.
Therefore, they are not readable by google, as your product claims.

Thanks
