Per the Google email snippet below:

================================================================
In December 2018, we announced our decision to shut down Google+ for consumers in April 2nd 2019 due to low usage and challenges involved in maintaining a successful product that meets consumers' expectations. We want to thank you for being part of Google+ and provide next steps, including how to download your photos and other content.

On April 2nd, your Google+ account and any Google+ pages you created will be shut down and we will begin deleting content from consumer Google+ accounts. Photos and videos from Google+ in your Album Archive and your Google+ pages will also be deleted.
================================================================

I've removed the Google+ button from the custom island. No impact to anyone here so business as usual.
