Hi, I lived in Japan, And I used a 530E bulb in my home with google home.

Yesterday, I bought one more 530E bulb, so I conncect that in my Tapo account. And it worked.

But, I cannot connet Tapo account to Google Home account. 
 

I changed my account, deleted and re-installed Tapo app, reconneted bulbs, changed Wi-Fi settings, but it doesn't work. 
 

Firmware is the newest one. What should I do?
