If an issue with Google services or products occurred, please try renewing your connection to Google Services. Please perform the following steps:
Open Google account settings (While signed in Google Account, click the username, then click Google Account to open the settings page).
Then select section "Security" or access via link: https://myaccount.google.com/security.
On this page, locate the "Third-party apps with account access" field and click "Manage third-party access".
If you select Conrad Connect and click "Remove access privileges", all connections to Google Services (Calendar, Google Fit, Google Sheets, etc.) will be removed.
In the "Sign in with Google" field, you can disconnect your Google Account from your Conrad Connect Account by clicking "Remove Privileges".
After logging in to Conrad Connect, please reconnect the desired Google Services under "Products & Apps".
