Disallowed Tag Error

Hi, love the ease of this plugin. I have an error with a disallowed tag present. It reports it on my chiefsays.com/AMP page I have the disallowed tag “animate”. The code with Animate in it begins with: <animate attributename=”opacity” …
I am a novice, so any recommendations on how to easily fix this would be appreciated. I don’t have much animation on my site.

Thank you!
