Hi @Stephen - can we ask, did you clear all caching after disabling 'advanced integration'?
We're not sure what errors you're still seeing or why an AMP test page would be used to check a URL?
If you can clarify that a bit, provide screenshots of what you're seeing, etc. we'd be in a much better position to help you.
It might also be worth checking that those plugins error messages are related to Ezoic by working with their support staff.
In past cases, simply disabling the advanced integration would resolve any issues with the stories pages.
Regarding removing the plugin, you're welcome to do this - if you were using the plugin for advanced ad integration, then those wouldn't necessarily 'stick' until you re-installed the plugin (with integration OFF). You'd want to review the site for placeholders once you disable the plugin and clear all caching.
