Traffic drop since launching Ezoic ads

After using Adsense for several years, I migrated over to Ezoic a few weeks ago. The ads have been live since 18.09, and you can see what's happened to my traffic since then.

Correlation doesn't always equal causation, but I think that Ezoic is at fault here.

Has anyone else encountered a similar issue? Any ideas for a potential fix?
