Consistent Need for Reauthorization

Hello. We have been using your plugin on multiple sites. It works well when it is initially setup, however over time the OAuth connection to Gmail expires and the site will stop sending emails.

Going through, revoking and readding the access makes it work for awhile longer, but after awhile it expires again. We have to correct this issue a few times a year. Now our clients are wondering why their site isn’t consistent.

I would love to be able to setup this connection and trust that it will keep sending.
