Unable to reconnect to new network or change network

So I am really frustrated. Had weak signal for my flood light cam and decided to put in a mesh network instead of adding an extender. Now have good signal strength but I cannto change the network that the camera is trying to connect to and can’t figure out why. There is NO change network option under device health, only the reconnect and so when I try to reconnect it doesn’t work and I am supposing it is because it is not the correct network as the network name is still the old one. Please tell me how to fix this. Tired of trying to find answer and support is not found anywhere.
