We're really sorry for the inconvenience caused. We have now reverted our changes so if you try again, you should find you'll now receive the authentication email as before.
Apologies again, please do verify whether it's now working or not.
It's working! Thank you for your help with getting this resolved quickly.
Shoutout to Fern, Stuart, and Anastacia for escalating this from a client perspective.
Could this also be affecting Khoros/ Spredfast Care Module, we are not receiving verification codes or any emails from Spredfast starting this moring and are unable to access the system. Any help would be greatly appreciated!
