Our upstream service provider has confirmed SMS delivery failures or delays. We will continue to monitor the situation and provide updates here as we learn more. At this stage we recommend avoiding the use of SMS as we are yet to understand if these are being queued for delivery of dropped by our service provider.
This affects OTP logins and SMS campaigns.
For administrators recommend switching to App Based 2FA login to Jomablue to avoid the SMS delays. If not already setup and you can progress due the sms issue, please email Jomablue support for assistance.
