I have talked to my community managers over at Google Ads, and they will not assist.
Basically, Google considers free listings as a complimentary feature, and so advertisers must use high quality data.
There is no reported bug with Google.
And that the free listings are subject to Google’s honest result policy: https://www.google.com/about/honestresults/
It is recommended for merchants to follow https://support.google.com/merchants/answer/9826542?sjid=17964466587427775763-AP

Please do not shoot the messenger, I am just relaying what they told me. So for those who had performance, may now need to re-check everything and make sure they have connected everything, added everything and improved everything.
Please note, I am not starting a debate, and again, only referring the info Google has given me. I am a Google Ads Product Expert and I can ask and get help for specific issues. The only times they don’t help, to ensure it is fair for everyone is related to free listings. It would be unfair if Google gives us product experts info regarding free listings that nobody else gets.
