Getting "The provided API key is expired." error on using Places API
I have faced same issue... But finally got resolved. Google place services will take 10 minutes to make the services available for new API KEY created. Services will start working after 10 minutes, till then we get error as "The provided API key is expired."
You have to activate the access in services in Google console by going to APIs then activate Places API
Make sure, your key is present in google play console or not. I had the same problem but when I checked my key on google place it was not there. It might be deleted by me by mistake or Google had deleted that key due to some reason. But by creating new key and I checked after 10 minute it is working.
