Serious bug

There’s a serious bug with your plugin adding a line to the schema data in the header, which Google marks as “Unparsable structured data report”. I’ve replaced the actual “domain” with domain for privacy.

{“@context”:”https://domain.zapwp.com/q:intelligent/retina:false/webp:false/w:1024/url:https://schema.org”

This causes rankings to drop off off a cliff. Furthermore, the link your plugin inserts into the first line of schema – “https://domain.zapwp.com” causes Succuri (and most likely other scanners) to detect malware. Thought you would want to know since this issue will likely affect a lot of users once Google’s spider hits their websites.
