  We are continuing our investigation. We believe the issue could be related to an ongoing GoDaddy incident involving SSL certificates (https://status.godaddy.com/incidents/mtl2b9tbvq56), although our certificate appears to be valid. We are investigating this potential connection. We will provide another update within 30 minutes or sooner if more information becomes available.

  The latest data shows that the add-in issue is global, although only a very small percentage of users are currently affected. We are continuing our investigation and looking more closely into the GoDaddy certificate incident as a potential cause. The next update will be provided within 1 hour, or sooner if we have new findings.
