Time slider stuck at 1 min in Edge on Android

I am using the one sec browser extension in Edge on Android since it can run extensions from the Microsoft store.

It mostly works very nice, but after the intervention time, a slider appears to set the allowed time, but the slider always stays at 1 minute and cannot be changed by either sliding or tapping.

A fix would be very nice :-)

As a cherry on top, it would be fabulous if the configuration page has a mobile layout to make the process easier.
