Can't get SmartThings linked to Google Home

I have a SmartThings 2018 wireless hub paired with all my dimmers and outlets, and all works fine from the CLASSIC ST app. But, I can’t get it to link to Google Home. It all worked a month ago, but then had to update my Wifi, and its been a struggle getting it all working again.

I’ve followed the online instructions at SmartThings, but no luck. Any ideas??

Thanks
