Ads delivering but no spend

I set up ad campaigns for 5 new products 5 days ago. I’ve only got 1 term but it’s fairly generic (birthday card for girl age xx) and there has been no spend whatsoever on any of them for 5 days. Nobody else sells my products so I have the buy box and I’ve tweaked the amount up from the 78p they suggested to £1 and they still aren’t being featured.

Does anyone have any idea what could be wrong?
