We have installed the application "Web Push Notifications" and followed the recommendations of the article https://stackideas.com/blog/get-notified-with-onesignal-web-push-notifications
but we are unable to receive notifications. The notification popup appears but it seems that we are unable to subscribe to push notifications.
We did tests on computers and on mobile, without success.
Do you think this could be a connection problem between the application and OneSignal ? Or an error somewhere?
You can find our contact details for the website https://app.onesignal.com
in "site details".
