Hi @masvil,
When Cloudflare Launched APo, one of their highest selling point was as APO uses KV storage it will cache the content across edge servers. But as Cloudflare makes rapid innovations that is not the case.
CF also launched Argo Smart Tiered cache which also does almost the same thing in a different way but achieve the same result. Initially Argo smart tiered cache was a paid product that was only available if you are paying for Argo.
But that is not the case anymore as CF has made the Argo Smart Tiered Cache free for all. Read this CF article: https://blog.cloudflare.com/orpheus/
As this plugin does not uses KV storage (to make sure you don’t get billed insane amount) and instead use the CF features that are free and gives you the most value. So, now when using this plugin if you enable Smart Tiered Cache in your account you will get your page cached across edge servers. Read the above article for more in-depth explanation.
