Hello,
Sorry for my English. I just developed an application under PowerApps, and I integrated push notifications to alert users during an incident. When changing the environment, I delivered the PowerApps Notification connector with the correct application ID, but I got an error message "The client certificate was not provided". I carried out several tests by uninstalling and reinstalling the connector, and by doing cross-tests but I find the same message. Since then, no user has received a notification. However in the old environment everything works fine. Do you have a solution?
