I can not remove avast from my tablet

I have an Asus Zenpad 3S 10 Z500M running Android 7 and I tried Avast recently but now I can not remove it. I deactivated the admin permission but still, when I uninstall, it redirects me again to manage the admin screen.

Hi,

Have you tried the uninstall processes in this guide? https://support.avast.com/en-ww/article/Uninstall-Mobile-Security/
When you uninstall via app settings, do you see the “Uninstall app” settings there?
