Cloudflare WordPress APO Expired Cache is not updated

I recently started using Cloudflare WordPress Automatic Platform Optimization. Cloudflare APO is working great and we saw a major increase in web performance. But the problem is when the Cloudflare APO cache expires, the cache is not rebuilt again.

Is this the normal behavior of Cloudflare or can we do something to ensure that the cache gets updated once it gets expired?
Also, Is this possible to clear the Edge cache after any WordPress Edits?
