Supports not showing up in Class Editor

Replies: 0

Before the WP 5.5 update, I created a CPT that only supports Title. After updating to 5.5, I wanted to add support for Featured Image.

I checked the Featured Image box under Supports for the CPT, but the option to choose a featured image didn’t show up when I tried to create a new post. I checked Screen Options to confirm that it just wasn’t there.

I switched from using the Classic Editor to the Block Editor and it showed up. If I switch back to the Classic Editor, it disappears again.

Ideally, I’d like to be able to use the Classic Editor with my CPT. Are you able to replicate this issue or is it happening only on my site?
