C3 Beta 110 just released and that disables WebGL 2 for the time being that should fix any withe screen or transparent sprites problem, it was a bug with GPU drivers. I bypased it in my small apps by just disabling WebGL in the Project properties but i understand that is not a good solution for bigger apps.
Anyone from EU could try my app to see if the consent dialog is showing?

From what i understand it should automatically show up since using the new version of the Mobile Advert Plugin right? Or do you actually need to put the action "Show consent dialog" On Start of Layout?
In the About screen i added the option to show it again whenever you want maybe you could try that.
