We have just released an updated to the behaviour of our RSS feeds. You are now able as an admin to expire al current RSS feeds in your Samanage account.
This action can be done under the Setup -> Notifications section as per the screenshot below:
Any RSS feed created anywhere in your account (e.g. incidents, assets etc.) will expire immediately upon pressing of the button and your users will be required to recreate their RSS feeds.
You should use this with caution as it will require as mentioned, for your users to recreate their feeds.
At your service,
The Samanage Team
