Concerns Over Limited Ads from Beehiiv Ad Network: Need for Variety

Hi, is there any particular reason why we're getting practically no ads from the Beehiiv Ad Network? Also, as someone mentioned before, the lack of variety is limiting performance. For some reason, we're only seeing ads from other newsletters, mostly within the same niche (and we've been getting the same types of ad opportunities from the same newsletters for several months now). There’s only one week left in the month, and we haven’t even reached 50% of the subscription plan cost. Are there any efforts underway to improve the situation or to build a more diverse ad network?
