"User cannot suggest edits to this question"

Question

Lately, I've been into edits using my new self phone, and all went smoothly.

But today, when I tried to suggest an edit to a new question, I simply couldn't.

Instead, I got this message: "User cannot suggest edits to this question".

Here is a screenshot, in case that helps.

As you can see, the message tells me that I can't, but it doesn't give me the reason why.

What I did (or didn't) to make the system reject my suggestion?

Is it a bug?

Answer 1

This is because while you are in the middle of making your edit, somebody else submits an edit that is still pending approval by users with at least 2000 reputation.
