We are continuing to work with our carrier partners on a fix for this issue.
Telenor has confirmed the issue is related to a connectivity issue that happened during their infrastructure migration which they are still working to resolve. For the other operators, we don't have any conclusive feedback yet but we're pushing this towards a faster response with them.
We will issue an update as soon as more information becomes available. Please contact firstname.lastname@example.org
if you have any questions.
