TopView - lost connection to Gmail account (Sign in with Google)

The following article is for TopView customers using a Gmail account to send/receive Email where authorization to the Gmail account was configured using "Sign in with Google" from the TopView Configurator > Email-SMS Notification > Outgoing Email.

Issue

Google is requiring users to allow "ongoing access" to the Gmail account. Without this option, the user will need to re-authorize every 6 months. 

Users who previously authorized TopView by "Sign in with Google" may lose current authorization in TopView. TopView will fail to send/receive email until the user reauthorizes by performing the "Sign in with Google" step again and enabling "ongoing access" (details below).

Alert
If you are using a Gmail account in TopView and it is not currently failing, we recommend that you remove the authorization and reauthorize using the steps below.
You can remove the authorization from the Configurator > Email-SMS Settings > Outgoing email screen:
