Slave MPP Solar 5048MK Bluetooth not recognised by Watch Power

[gonediving]

I have two MPP Solar 5048MK inverters operating in parallel. Previously, both connected to Watchpower via Bluetooth. After being away for a month, now only the master inverter is visible in Watchpower. The slave inverter is not.

Both inverters have the Bluetooth logo visible in the LCD readout

Both inverters have paired with my android phone

I've noted previous comments about having Location turned on for Watchtower so I have turned it off and on again.

I've uninstalled and reinstalled Watchtower (Bluetooth not WiFi)

Does anyone have any ideas on how to connect my slave inverter to Watchpower via Bluetooth?

Thanks

To answer my own question: I restarted my phone and all seems ok now both inverters are visible within Watch power
