We (The Turing Trust) have invited a partner, who is going to help us with content creation, to edit our test channel. However, when he tries to activate his account to be able to access the channel, he keeps getting the message
"Failed to activate account. Please try again."
Although this has been posted before, the response was to contact the person who was having the problem to support them, so it isn’t clear what the problem was.
I would appreciate some help with this - and can provide contact details for support if required.
