Settings → Network & Internet → select your connection (WiFi or Ethernet) 2. Scroll down to DNS server assignment → click Edit 3. Change to Manual, toggle on IPv4, enter 1.1.1.1 or another trusted DNS resolver 4. Click Save If you are not familiar with making these changes or your devices are managed by your organization, please reach out to your IT or infrastructure team for assistance. We are actively working to resolve the underlying issue. We will provide updates as we have them.
