Same here. Cannot use vacation mode because I sell on individual title, not as a business. Went to do my usual reactivation after dormancy (been doing this for the last year or so as I have been busy with work) which worked, but am now faced with needing to apply to sell LEGO (on Amazon.ca), and "Not authorized to sell" on Amazon.com.
I knew I was playing with fire and at this point will just take it. EBay and Bricklink are more relaxed avenues to sell for casuals like me.
