Thank you for reaching out and sorry to hear you are facing trouble activating few fonts. It does look an issue with your account. Could you please check if you're able to activate the fonts from here: https://fonts.adobe.com/fonts/sofia? If no, please share your Adobe ID with me from which you updated your plan over a private message.
Note: Please add the URL of this post over a PM for reference.
I will try my best to help.
