new wifi with same name and password, Meural wont connect

Hi, 

I recently purchased Google Mesh access points to help with some external smart cameras located outside the house.

. I used the same network name and password for it as my old network as I hoped it would reduce the workload of reconnecting the smart devices.

 I disabled the AP on the old router.  We have a a lot of 'smart' devices... each one needed to be reconnected to the new network ( PITA).. a couple required a reset as they seemed confused ( would not connect to the new network ) because the same network name was  different piece of hardware.  Factory resets solved that. 

We have a Meural Canvas II MC327. It wont connect. It keeps saying wrong wifi name or password error during the setup. 

These are the steps I've done  ( incrementally as each one didn't work, I kept trying more invasive resets...) . 

-I did a factory reset of the hardware. 

-I deleted the app on my iPhone and reloaded it. 

-I used a new device previously not connected to it. 

-I deleted the device from the Meural app. 

-I removed my firewall. 

All did not help. The error remained the same. 

I created a new guest network with a new SSID and it connects no issue. 

I'd prefer not to have an extra SSID just for this device. 

Is there a way to flush the cache somehow ( is it cached on the Meural website ?  or ?? ) 

Any ideas ? 

Thanks
