guiderman Thank you for sending this over it is really helpful for us to see what you are seeing. The warning message that you are seeing in Google adsense can be safely ignored. Google is not seeing Ezoic's ads.txt and thinks you don't have one set up which is why you are getting the message.
With Ezoic your ads.txt is set up here https://pubdash.ezoic.com/ezoicads/adtransparency/adstxt and you can verify that it is all set up correctly by using the validator button. I have just tried this now and it is all working ok.
