Competitive price

I had 1 unit which had some scratches so I didn’t wanna sell it on Amazon, I instead put the listing on ebay with the same listing images, title and description I use on amazon.

Since then I lost my competitive price check and buy box.

I deleted the listing on ebay altough it is still visible through a google search, I just sent an email to ebay asking to fix that.

Do you have any idea how long it’s gonna take to get back my competitive price? How often they check off-amazon prices?

Thanks
