I'm in the process of leaving as well. They eventually wrote back with a
"sorry, some automated systems are incompatible" message. For example,
can't authenticate 2FA on my Twitter account.
I had opened a ticket almost 2 weeks ago, got the "48 to 72 hours"
message. A week later I received a follow-up email that it would be
another 48 to 72 hours. That was 96 hours ago...
Having the exact same issue. One of the automated systems is my child's
school bus notification system, which is reports back as "incompatible
network." If this isn't fixable I'm going to have to switch back to a
mainline network.
