Soon I'll be migrating my website from GoDaddy to Blogger. I haven't been able to configure Blogger to allow ads. Adsense does not recognize my ads.txt file.
I want to know how will this affect my relationship with Ezoic.

Are you planning to move your site to blogger to reduce your hosting costs?
If your site is built with WordPress, you may want to switch to Ezoic WP Hosting instead. Ezoic Dashboard -> Settings -> Hosting
