Tuya wifi security camera woken by motion but not app live stream

[Tom128NZ]

Hi

I have found lately my tuya app has been unable to wake 3 of my 4 security cameras. The motion sensor can wake them and can then live stream to the tuya app and all signals are mid 60%-90%. Does anyone have any ideas about what could be causing this?

Below are the steps I have tried;

Router Reset
Camera reset / uninstall - reinstall
Tuya app uninstall - reinstall
Change of wifi name

Thanks in advance for any help.
