Admin Edit post does not appear on admin bar inside an article

Hello,

Today<span style=”box-sizing: border-box; margin: 0px; padding: 0px;”>, I encountered this problem: When I am logged in as an Admin user, the “Edit post” in the admin bar of the front-end does not appear. I want to point out that the admin role is excluded from caching, and I have also disabled caching for logged-in users</span>. I also switched on and off in

I troubleshoot the problem using the LSCWP_CTRL=NOCACHE parameter, and I saw that the button appeared. After disabling most of the admin-related options (and even logged-in user and admin user roles were not cached), I then disabled the ESI setting, and the bar appeared. I have excluded the caching of the admin bar, but the problem still appears.

Can this be a bug related with the settings of ESI, or is there any other approach on this?

Conflicts with themes or plugins were tested, and none were found. If it was a problem after all, then the LSCWP_CTRL=NOCACHE parameter that serves the purpose would not solve the problem.

Let me know your thoughts/approach on this.
