# I'm getting this error message after upgrading to 1.7.5. I do not have the MEDUSA_FF_SALES_CHANNELS flag set, so don't expect to see this message. I tried downgrading to 1.7.3 but still get the message. Did something change recently?
# Hey! You just have to assign a sales channel to already existing products in the admin. Had the same issue aswell after upgrading to 1.7.5
