phone silencer app

[robthirlby]

I have used an app called phone silencer for years but since my device upgraded to android 9 it no longer works.
I need an app that silences the phone for a period and then reverts to normal for theatre performances and meetings. I'm not interested in scheduled silences. Any recommendations or fixes?

Volume Controls by Ali Kamalizade has a silent setting, but you need to do it manually
