Shelly Button 1 - not recognising button pushes

Recently all my Shelly Button 1’s have stopped recognising any button push.

I have 6 set up for different automations. I have the latest Shelly firmware and have tried deleting them and re-adding them.

Battery level shows up.

Location shows up.

Shelly Button 1 flashes green as though it has communicated successfully (normally red if fail)

No button push shows up in logs.
