Hi, @Egoswim !
Is this happening on products with variants? If so, and if the price displayed matches one of your variant prices, then I suggest checking out this information that I previously shared for some next steps:
If the prices on Facebook are displaying the correct price for your most expensive variant, then I recommend reaching out to Facebook via their Business Help Center for more information on how they display product prices on their end.
However, if the product prices showing on Facebook’s end don’t match any of your variant or product prices, then please submit a support request to our team via our Help Center using this link. That way, our team can verify your account, and help look into this further.
Thanks!
