Please remove the limit from free ads so that you can not specify it. For example, I will set a limit of 10 for a free ad, the seller will publish an ad and choose a free placement, and when the seller places 2 ads once, he will not be able to select a package until the limit expires, and if you set a limit of 1 ad, then 2 times can not be selected. Please make sure that every time you are asked which package to choose and that you can not choose the limit on the free ad
Thanks will consider adding this option. You can try setting some low free limit as a workaround, e.g. 1 free ad, or more ads with a low expiration date (so users will also exceed this limit on renewals).
