Updating Article Doesn't Purge APO Cache

When updating an already published article, APO doesn’t purge the cache and an old version of the page is served.

Is this expected behavior?

I have the same problem. And need to manually purge the cache

I’m certainly seeing site speed benefits, but this can’t be the expected behavior, right?

UPDATE (8/30): This seems to be fixed for me. Not sure if there was a Cloudflate change or not
