I reached out to Customer Care and this is the response I got:
"We're aware this is affecting some users and are working to resolve this as quickly as possible.
If anything changes or the issue resolves itself, please let me know. In the meantime, thank you for your patience and apologies for any inconvenience this may be causing.
