Address goes grey

Hello @vivkiaustralia,

Greetings!

Regarding your question, since this issue is not reproducible in our test environment, could you please let us know whether your Google API is activated in your Google Cloud Console, which will get activated after you add your billing information to the Google Console? Also, kindly let us know whether you are using any checkout field editor plugin on your site as there is a probability of compatibility issue.

Please find an article for your reference:

Looking forward to hearing from you soon.
