@David_K, thanks for the help.
@Jpopooo, we'll do our best to get you the support you need however, this channel is for troubleshooting Google Nest devices. It is best to report this with JBL support for better assistance if we're not able to get this resolved.
To start with, try the steps below:
If your speaker or display isn’t connected to a Wi-Fi network. Set up your speaker or display on the new Wi-Fi network:
If your speaker or display is connected to an existing Wi-Fi network, but you'd like to connect it to a new one, follow the steps below:
If you get an error message that says "could not communicate with your [device]" when you try to forget your network, or the steps above don't work, you'll need to factory reset your device and set it up again. For the factory reset, since it may be different from our Nest devices, it would help a lot if you could reach out to JBL directly for directions on how to.
Hope this helps.
