Google Sheets Connector not updating

My dashboard works but the data connection is often problematic.  Randomly, I'll pull up the dashboard and it will show data connection errors to my Google Sheets data.  Today I opened it and it's not showing any errors but it's clearly operating on data cached from weeks ago.  I've refreshed fields, refreshed the connection, even disconnected Looker Studio and reauthorized it, but it still isn't showing updated data.  It is so problematic as to be untrustworthy for regular use.  Does anyone else have the same issues?
