No, there’s an A/B implementation going on. The UBO maintainers hadn’t seen the crackdown themselves and had to rely on troubleshooting reports to see what is going on which is wild to think about - both on their skill but also did google specifically whitelist them or are they exceptionally lucky
There really was some ads that get through last month, but UBO fixed that last week. Either you got lucky or you are not in that set - Google do A/B updates before.
