ReadyNAS316 - Email notification won't work from 8 July 2020

The service still works - my point is that it is going to stop working from 8 JULY 2020 (according to the email I received).

I'd like to know if Netgear/ ReadNAS is aware of this and if something could be done to keep the Google Notification service running after 8 July 2020.

Firmware = 6.10.3

The full wording of the email is as follows;

Hello,

Beginning 8 July 2020, the following app will no longer have access to your Gmail data

Google has always worked to design our tools and services with security at their core. Last year, we proactively updated the Google user data policy to better protect Gmail users.

All apps listed above have not passed our required verification process and, as a result, will no longer be able to access your Gmail data starting 8 July 2020.

Without access to your Gmail data, this app may not work as intended. If you have any questions, please contact the developer of the app.

You can also use the Security Check-Up tool to view, manage and remove any apps that you have given access to your Google Account.

Thanks,
The Google Accounts Team
