Speed sensor not connecting

Not sure if it’s user error or a known bug but ever since the latest Android update I’m unable to connect my wahoo speed sensor.

Heart rate connects fine, cadence is hit and miss but speed won’t show at all.

Setup:
Samsung s7 running Zwift
Wahoo HR, cadence sensor, speed sensor
Dumb trainer

As I say, things were working until the last update and now they’re not.

Any pointers are greatly appreciated.

When’s the last time you changed the battery on that speed sensor?

Probably a couple of months ago as it was a brand new unit.

So I’ve changed the battery in both the speed and cadence sensor and reinstalled the app and it’s still not picking up the sensor, just constantly searching

Is there anything else I could try?
