Good to know it's not just me. Give me a heads up if you find out the cause.@Arequire I've installed the Brave Browser and I have the same issue, it's something related to the browser. This is strange because this is a Chromium based browser so it should not have issues... I'll see if I can find the cause.
You will just need to dismiss the Push Notification banner (click on the X in the right corner, then Never ask again) until this gets fixed, it's not our fault, it is related to something that the browser does differently that the other Chromium builds.
