I too can confirm this problem is NOT solved as I am having direct access issues with /.well-known/shopify/monorail/unstable/produce_batch and /Liquid with appears to be a script.
In addition the IPs are fake and the traced source shows them out of the country.
ALL of this points to direct interference from bad Actors trying to twart the effectiveness of the website in some manner:
either Reduction of speed, reducing access to the prodcuts, causing 404’s and perhaps all with the intention of reducing the Page Authority for rankings as this traffic is all ending up in Google Analytics.
Bottom line: This is intentional and Mal intented Traffic.
This is not just a Technical Glitch in the structure of the Shopify Store code.
We Need PROTECTION by Shopify and their Technical Support ATTENTION to this matter.
HOW do we get them to be serious and elevate these issues?
