While many ad platforms have cut back due to the above and big advertisers are switching around budgets, there are many other things going on in the background at many top tier networks atm (adwords and FB i'm looking at you) that are causing unusually long ad review processes and all sorts of issues. What issue are you having? Just having issues getting ad accounts approved, or getting ads approved? or getting ads profitable?Is this a sign of the times? Am I running into the washout of the Facebook-Russia thing, the Cambridge Analytics story? Everyone seems hesitant to accept ads. "Please take my money!", "Nah, we don't want it"
FWIW I just spent 1 month getting approved for a well known Native network and they say it's their new normal right now.
