Product discount error

I tried to add a discount on my product but I face an error during the process “To be eligible for a discount, an item must have had the same price for at least 30 consecutive days.”
I’m sure that I haven’t changed the product price at all.

What is the problem?
Note: I have a discount on the product 30 days ago.

Thank you.

That’s weird. I can see from web archives that your price has indeed not changed, unless it was but for a short moment. :thinking:

The good news is that it looks like the 30 day window will expire in about 10 hours, after which you will be able to set the discount.
