I don’t tinker with APO that often. But if you check the Audit Log from dash.cloudflare.com, can you see which Purge Cache is triggered? Is it a Purge Everything, or it it just some Purge URLs?
Good news, it will be really helpful for people with blogs and pagination. I did not figure this out, some readers emailed me about it when they saw some missing posts.
I know we all complain about something here, but @yevgen rest assured we appreciate all the work you put into making APO better every day.
