I have created API key for TimeZone API and restrict it by check on TimeZone API checkbox in restriction and upload apk to google store but after some days google gave alert that Your app contains exposed Google Cloud Platform (GCP) API keys. If i restrict API key with release SHA1 and package name then API key not working and gave response
{"errorMessage":"This IP, site or mobile application is not authorized to use this API key. Request received from IP address 39.57.167.49, with empty referer","status":"REQUEST_DENIED"}.
Please suggest what should i use to avoid google console warning.
